marketing company focused on computing and Internet-related technology, with
principal platforms in print publishing, trade shows and conferences, online
content, market research and education. The Company provides global technology
companies with marketing strategies for reaching key decision-makers.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the top
three computer magazines in the U.S. and are among the top 25 U.S. magazines,
each as measured by total revenue in 1996 (the latest year for which data is
available). The Company also produces the world's most important trade shows
serving vendors, resellers, buyers and users of computer technology, including
COMDEX/Fall, the largest trade show in the U.S. The Company's ZDNet.com Web

the U.S. in terms of total magazine revenue. In that same year, Ziff-Davis
accounted for 36.8% of all advertising and circulation dollars spent in
computer periodicals, with at least 50% more total magazine revenue than its

and advertisers is based on its comprehensive market and product coverage, the
quality of its editorial content and the influence of its readership.
 
  In 1997, the Company produced over 50 trade shows and conferences worldwide
with over two million estimated attendees. The Company's COMDEX/Fall event is
the number one ranked trade show for all industries in the U.S. as measured by
total revenue, total exhibit space and number of attendees.
 
  The Company's other media and marketing platforms include online content,
market research, education and the publication of computer-related newsletters
and training manuals and materials. In addition, the Company has an option to
acquire an interest in ZDTV: Your Computer Channel ("ZDTV"), the first 24-hour
cable television channel and integrated Web site focused exclusively on
computers, technology and the Internet, which is expected to be launched in the
first half of 1998.

  The Company had total revenue of $1.154 billion for 1997. The Company's
revenue is primarily derived from advertising sales, which represented 51.9% of
total revenue in 1997. The second largest component of the Company's revenue is
derived from trade shows and conferences, which accounted for 23.5% of total
revenue in 1997. Circulation revenue, comprised of subscription and newsstand
single copy sales, generated 13.1% of the Company's revenue in 1997 and other
revenue components, including online content, market research and revenue
derived from joint ventures and licenses, contributed 11.5% in 1997. The
Company had a net loss of $71.2 million for 1997 and will report a loss from
operations of $24 million for the first quarter of 1998 as compared with a loss
from operations of $15.6 million for the first quarter of 1997. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."     
 
BUSINESS AND OPERATING STRATEGY
 
  The Company's objective is to be the preferred marketing partner to
technology vendors and service providers seeking to reach primary decision-
makers involved in the specification and purchase of their products and
services. Major elements of the Company's strategy include:
 
  .Maintain Focus on the Computer and Internet Technology Markets
 
  .Develop the Most Comprehensive, Objective and Authoritative Content
 
  .Build Upon Brand Strength of Existing Media Properties
 
  .Continue to Leverage Multiple Media Marketing Platforms
 
  .Expand Leadership on the Internet
 
  .Launch New Products and Services
 
  .Expand Global Reach
 
  Although none of the proceeds of the Offerings will be paid to the Company,
the Company expects to fund its business and operating strategy from internally
generated cash flow from operations, which are estimated to be sufficient to
fund investments and the repayment of indebtedness. As a result of certain
large non-cash charges, the Company's earnings for the year ended December 31,
1997 were insufficient to cover fixed charges by $74.5 million and, on a pro
forma basis, by $6.8 million. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

RELATIONSHIP WITH SOFTBANK
 
  Upon the completion of the Reorganization described below, SOFTBANK Corp., a
Japanese corporation publicly-traded on the Tokyo Stock Exchange First Section
(together with its affiliates, "Softbank"), will own approximately 74.2% of the
outstanding shares of Common Stock (71.4% if the U.S. Underwriters' over-
allotment is exercised in full). The Company and Softbank have entered into
certain agreements governing various interim and ongoing relationships between
Softbank and the Company. Softbank also has given the Company an undertaking
not to expand certain operations outside Japan in competition with the Company
without the prior approval of the Company's management directors after
consulting with the Company's independent directors. This undertaking would not
preclude investments by investment funds managed by Softbank. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest," "The Company--Relationship with Softbank" and "Certain
Transactions."
 
  The following table presents Softbank's total historical investment in and

                               THE REORGANIZATION
 
  The Company is an indirect subsidiary of SOFTBANK Corp., which, as of
December 31, 1997, was 50.2% owned by Mr. Masayoshi Son, its President,
including 43.4% directly held by his 99% owned holding company, MAC Inc., a
Japanese corporation ("MAC"), and SOFTBANK Corp.'s largest shareholder. Prior
to the Offerings, the Company's businesses were conducted through various
indirect subsidiaries of SOFTBANK Corp. The Company's publishing business was
principally conducted through Ziff-Davis Inc. ("ZDI") and its trade show
business was principally conducted through ZD COMDEX and Forums Inc. ("ZDCF").
The MAC Assets were managed by ZDI and ZDCF, but were owned by MAC.
Concurrently with the Offerings, the Company will consummate a Reorganization
(as described under "The Reorganization") pursuant to which: (i) all of the
stock of ZDI and ZDCF will be contributed to the Company by Softbank in
exchange for 74.2% of the Company's Common Stock; (ii) the Company will
complete the purchase of the MAC Assets; (iii) the Company will issue and sell
the Common Stock and the Notes pursuant to the Offerings; (iv) the Company will
enter into a credit facility with a group of financial institutions (the
"Credit Facility") and borrow $1.25 billion thereunder; and (v) approximately
$928 million of the Company's obligations to Softbank will be converted to
equity and the Company will repay approximately $1.531 billion of obligations
to Softbank. The Company has obtained a commitment letter from The Bank of New
York, Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase
Manhattan Bank to provide such Credit Facility. All of the transactions
comprising the Reorganization will be deemed to occur simultaneously. See "Risk
Factors--Risks Relating to the Reorganization," and "--Absence of History as a
Stand-Alone Company; Limited Relevance of Historical Financial Information,"
"The Reorganization" and "Unaudited Pro Forma Combined Financial Information."

              SUMMARY HISTORICAL COMBINED FINANCIAL AND OTHER DATA
 
  The following table presents Summary Historical Combined Financial and Other
Data for ZDI and ZDCF as of December 31, 1997 and for the three years then
ended which were derived from the audited combined financial statements of ZDI
and ZDCF included elsewhere in this Prospectus. COMDEX was acquired by Softbank
on April 1, 1995 and ZDI was acquired by Softbank on February 29, 1996; the
Summary Historical Combined Financial and Other Data includes the results of
COMDEX and ZDI from such dates. See "The Reorganization." The following table
also presents pro forma combined financial data of ZDI and ZDCF giving effect
to the transactions described under the heading "The Reorganization" as if they
had occurred as of January 1, 1997, in the case of the statement of operations
data, and as of December 31, 1997, in the case of the balance sheet data. The
pro forma financial data does not purport to be indicative of the results that
actually would have been obtained had the Reorganization been completed as of
such dates and is not intended to be a projection of the future results of
operations or financial position of ZDI and ZDCF. The following information
should be read in conjunction with "Use of Proceeds," "Capitalization,"
"Selected Historical Combined Financial and Other Data," "Unaudited Pro Forma

(1) Due to the subjectivity inherent in the assumptions concerning the timing
    and nature of the uses of cash generated by the pro forma adjustments, cash
    flows from operating, investing and financing activities are not presented
    in the pro forma data.
(2) No historical earnings per share or share data are presented as the Company
    does not consider such data meaningful. Upon closing of the Offering, 100
    million shares of common stock will be outstanding and pro forma earnings
    per share data gives effect to these shares as if they were outstanding on
    January 1, 1997.
(3) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. EBITDA is not intended to represent
    cash flows from operations and should not be considered as an alternative
    to net income as an indicator of the Company's operating performance or to
    cash flows as a measure of liquidity. The Company believes that EBITDA is a
    standard measure commonly reported and widely used by analysts, investors
    and other interested parties in the publishing and media industries.
(4) For purposes of the computations, earnings before fixed charges consist of
    income/(loss) before income taxes adjusted for equity earnings (loss), as
    appropriate, plus fixed charges. Fixed charges are defined as interest
    expense plus that portion of rental expense which is deemed to be
    representative of the interest factor. For the years ended December 31,
    1996, 1997 and Pro Forma 1997 earnings were insufficient to cover fixed
    charges by $26,598, $74,520 and $6,805, respectively.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves various
risks. Prior to investing in the Common Stock being offered hereby,
prospective investors should consider carefully the factors set forth below,
together with the other information set forth in this Prospectus. Certain
information contained in this section and elsewhere in this Prospectus
contains forward-looking statements which involve risks and uncertainties. The
Company's actual results could differ materially from those anticipated in
these forward-looking statements as a result of certain factors set forth in
this section and elsewhere in this Prospectus.
 
RISKS RELATING TO THE REORGANIZATION
 
  The Company is a newly organized Delaware corporation, incorporated on
February 4, 1998 in contemplation of the Reorganization. As part of the
Reorganization, the Company has acquired and will acquire the MAC Assets for
approximately $370 million. Although the Company believes that the purchase
price does not exceed fair market value, such arrangements are not the result
of an arm's length negotiation between unrelated parties, and there can be no
assurance that the Company would not have been able to obtain better terms
from unrelated parties. See "The Reorganization," "Unaudited Pro Forma
Combined Financial Information," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Certain Transactions."
 
ABSENCE OF HISTORY AS A STAND-ALONE COMPANY; LIMITED RELEVANCE OF HISTORICAL
FINANCIAL INFORMATION
 
  The Company has never operated as a stand-alone company. Until October 1997,
the ZDI and the ZDCF businesses were managed as separate Softbank
subsidiaries. The Company's future operating results will depend in part on
its ability to integrate these businesses and manage the combined enterprise.
In addition, although the Company will be a subsidiary of Softbank following
the Offerings, Softbank will be under no obligation to provide assistance to
the Company or any of its subsidiaries.
 
  The financial information of ZDI and ZDCF included herein does not reflect
what the actual results of operations, financial position and cash flows of
the Company would have been had the Company existed and the Reorganization
been completed prior to the periods presented, nor is it necessarily
indicative of the results of operations, financial position and cash flows of
the Company in the future. The financial statements also include the MAC
Assets which are being transferred to the Company pursuant to the
Reorganization. See "Unaudited Pro Forma Combined Financial Information,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Presentation of Financial Information" and "Certain Transactions."
 
CONTROL BY PRINCIPAL STOCKHOLDERS AND POTENTIAL CONFLICTS OF INTEREST
 
  Upon the completion of the Reorganization, Softbank will own approximately
74.2% of the outstanding shares of Common Stock of the Company (71.4% if the
U.S. Underwriters' over-allotment option is exercised in full). As a result,
Softbank will be in a position to direct the election of all members of the
Board of Directors of the Company and to control even those actions that
require the approval of two-thirds or more of the voting share capital of the
Company, including amendments to the Company's Certificate of Incorporation
and any business combinations. Such concentration of ownership would also have
the effect of preventing a change in control of the Company that might
otherwise be beneficial to stockholders. Section 141 of the Delaware General
Corporation Law, however, imposes upon directors a fiduciary duty to
shareholders.
 
  The Company and Softbank have entered into certain agreements governing
various interim and ongoing relationships between Softbank and the Company,
including certain licensing and management agreements relating to
publications, trade shows, ZDTV and ZDNet. In addition, Softbank has given the
Company an undertaking that, as long as it owns 40% of the voting stock of the
Company and can elect a majority of the Board of Directors, it will not expand
operations involving (x) publishing information on computing and Internet-
related technology through the media of print, CD-ROM/DVD, Internet and
television, or (y) producing trade shows, conferences, exhibitions and similar
events primarily related to computing and Internet-related technology outside
Japan in competition with the Company without the prior approval of the
Company's management
 
                                      12
<PAGE>
 
directors after consulting with the Company's independent directors. This
undertaking does not preclude investments by investment funds managed by
Softbank. Softbank manages certain venture capital funds which invest in,
among other things, computer and Internet-related companies. These funds may
be able to co-invest with the Company or compete with the Company with respect
to new investments. Softbank may develop new funds in the future, which funds
may compete with the Company for investment opportunities. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. Such arrangements and undertaking are not the result of an arm's length
negotiation between unrelated parties. See "--New Product Risks," "The
Company--Relationship with Softbank," "Certain Transactions," "Principal
Stockholders" and "Description of Capital Stock."
 
SIGNIFICANT DEBT OBLIGATIONS
 
  At December 31, 1997, on a pro forma basis after giving effect to the
Reorganization described under "Unaudited Pro Forma Combined Financial
Information," the Company's total debt was approximately $1.594 billion, its
total stockholders' equity was approximately $1.441 billion, its earnings were
insufficient to cover fixed charges by $6.8 million and its total debt was
52.5% of total capitalization. The Company's indebtedness is substantial in
relation to its stockholders' equity. The degree to which the Company is
leveraged could have important consequences to holders of Common Stock
because: (i) the Company's ability to obtain additional financing in the
future for working capital, capital expenditures, acquisitions or general
corporate purposes may be impaired; (ii) the funds available to the Company
for its operations may be reduced if a substantial portion of the Company's
cash flow from operations is dedicated to the payment of principal and
interest on its indebtedness; and (iii) the Company's ability to incur
additional debt may be impaired because the Credit Facility and the Notes
contain financial and other restrictive covenants, including those relating to
the incurrence of additional indebtedness, the creation of liens, the payment
of dividends and sales of assets. See "Description of Certain Indebtedness."
The indebtedness of the Company requires a substantial portion of the
Company's cash flow to be dedicated to the payment of principal and interest
on indebtedness, thereby reducing funds available for capital expenditures and
future business opportunities. In addition, the Company's indebtedness could
increase the Company's vulnerability to adverse general economic conditions
(including increases in interest rates) and could impair the Company's ability
to take advantage of significant business opportunities that may arise.
 
DEPENDENCE ON DEMAND FOR ADVERTISING
 
  A significant portion of the Company's total revenue in 1997 (51.9%) was
derived from advertising sales. Should a general economic downturn or a
recession in the United States occur in the future, the Company's advertisers
may reduce their advertising budgets. In addition, technology product
advertisers may be affected by factors such as pricing pressures and new
product launches. Furthermore, there can be no assurance that technology
product advertisers will maintain current levels of advertising in special
interest magazines and events as opposed to general interest media such as
newspapers, television and Internet sites. Any material decline in the demand
for advertising by technology product advertisers could have an adverse effect
on the Company's financial condition and results of operations.
 
IMPORTANCE OF CERTAIN PUBLICATIONS AND TRADE SHOWS
 
  Certain of the Company's publications have represented a significant portion
of the Company's historic revenue, and the Company expects that such
publications will continue to do so in the future. The Company's business
publications, which include such titles as PC Magazine, Computer Shopper and
PC Week, accounted for 65.3% of the Company's publishing revenue in 1997.
Although the Company believes it has a diversified portfolio of special-
interest publications and is not dependent on any single publication, a
significant decline in the performance of any of these publications could have
an adverse effect on the Company's financial condition and results of
operations. See "Business--Print Publishing--Sources of Print Publishing
Revenue."
 
  Certain of the Company's trade shows and conferences have represented a
significant portion of the Company's historic revenue, and the Company expects
that such trade shows and conferences will continue to
 
                                      13
<PAGE>
 
do so in the future. COMDEX/Fall accounted for 34.0% of the Company's trade
show and conference revenue in 1997. Although the Company believes it has a
diversified portfolio of trade shows worldwide, a significant decline in the
performance of COMDEX/Fall could have an adverse effect on the Company's
financial condition and results of operations. See "Business--Trade Shows and
Conferences--Sources of Trade Show and Conference Revenue."
 
SEASONALITY OF REVENUE; FLUCTUATIONS IN REVENUE FROM PERIOD TO PERIOD;
ANTICIPATED LOSS FOR FIRST QUARTER OF 1998
 
  The Company's business is seasonal, with revenue typically reaching its
highest level during the fourth quarter of each calendar year, largely due to
the timing of its single largest trade show event, COMDEX/Fall, and the
increase in publishing revenue in the fourth quarter due to increased consumer
buying activity during the holiday season. In 1997, 35.0% of the Company's
revenue was generated during the fourth quarter, with the first, second and
third quarters accounting for 19.5%, 26.1% and 19.4% of revenue, respectively.
In addition, the Company may experience fluctuations in revenue from period to
period based on levels of marketing expenditure by the Company's advertising
customers and by competition among computer technology marketers. Many of the
Company's large customers concentrate their advertising expenditures around
major new product launches. Marketing expenditure by technology companies can
also be affected by factors affecting the computer industry generally,
including changes in end user demand, pricing pressures and inventory
surpluses. Furthermore, the Company's results are affected by the number and
timing of new product launches and the timing of events. The launch of new
publications, trade shows and services are funded with cash flow from
operations and are expensed as incurred. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Overview" and "--
Seasonality."
 
  For the first quarter of 1998, the Company will report a loss from
operations of $24 million as compared with a loss from operations of $15.6
million for the first quarter of 1997. There are several factors influencing
the lower operating results for the first quarter of 1998, including lower
advertising revenue in the Company's business publications as a result of
factors affecting the computer technology industry generally (substantially
offset by revenue from trade shows which were not held in the comparable
period of the prior year) and certain one-time costs occurring in the first
quarter of 1998. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Three Months Ended March 31, 1998
Compared With Three Months Ended March 31, 1997 (unaudited)."
 
HISTORICAL NET LOSSES
 
  The Company had net losses of $52.1 million and $71.2 million for the twelve
months ended December 31, 1996 and 1997, respectively. On a pro forma as
adjusted basis giving effect to the Reorganization, the Company had a net loss
of $7.9 million, or $(.08) per share, for the twelve months ended December 31,
1997. See "Unaudited Pro Forma Combined Financial Information." There can be
no assurance that the Company will report net income in the future.
 
NEW PRODUCT RISKS
 
  The Company's future success will depend in part on its ability to monitor
rapidly changing technologies and market trends and offer new publications,
trade shows and services that address the needs of specific target audiences.
The process of internally researching and developing, launching, acquiring
acceptance and establishing profitability for a new publication, trade show or
service, or assimilating and marketing an acquired publication, trade show or
service, can be risky and costly. There can be no assurance that the Company's
efforts to introduce new or assimilate acquired publications, trade shows or
services will be successful or profitable. In addition to its publications,
trade shows and services, the Company is a leading provider of Internet
content about computing services, primarily through its ZDNet online service.
The Internet is still in the relatively early stages of development;
therefore, there can be no assurance that the Company's Internet services will
remain competitive. Costs related to the development of new products are
expensed as incurred and, accordingly, the Company's profitability from year
to year may be adversely affected by the number and timing of new product
launches. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
  The Company has entered into a license and services agreement with MAC to
develop ZDTV. ZDTV is indirectly owned by MAC, but as part of this license and
services agreement MAC has granted the Company an
 
                                      14
<PAGE>
 
option exercisable through December 31, 1998 to purchase all of MAC's interest
in ZDTV for an amount equal to MAC's investment plus 10% per annum for the
period of its investment. The Company does not intend to exercise the option
unless ZDTV has secured sufficient cable carriage. This may include entering
into a joint venture or other co-ownership arrangement. The Company is
currently funding ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. ZDTV's cash requirements are expected to be approximately $54 million in
1998. There can be no assurance that MAC will continue to approve and
reimburse the Company for expenditures or that the Company will exercise its
option. If the Company exercises its option, there can be no assurance that
ZDTV will ultimately obtain sufficient cable carriage and commercial
acceptance to be profitable. See "The Company--Relationship with Softbank" and
"Certain Transactions."
 
RISKS ASSOCIATED WITH FLUCTUATIONS IN PAPER AND POSTAGE COSTS
 
  The Company's principal raw material is paper. Paper costs constitute a
significant expense, accounting for 15.2% of the Company's total U.S. print
publishing operating expenses in 1997. Paper prices have been volatile over
the past several years, initially rising in 1994, rising more significantly in
1995 and 1996 and declining in 1997. Management anticipates paper prices will
increase in 1998. The Company does not use forward contracts and most of its
paper supply contracts, which are generally for a two to three year renewable
term, provide for price adjustments to reflect changing market prices.
Accordingly, significant increases in paper prices could adversely affect the
Company's future results of operations.
 
  Postage for magazine distribution is also a significant expense for the
Company, accounting for 11.3% of the Company's total U.S. print publishing
operating expenses in 1997. Postage costs increase periodically and can be
expected to increase in the future. The United States Postal Service has
recently announced a 5.4% increase for commercial magazine rates, which is
expected to become effective in 1998. The Company may not be able to recover,
in whole or in part, paper or postage cost increases. Accordingly, significant
cost increases could have an adverse effect on the Company's financial
condition or results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business--Print
Publishing--Paper and Printing."
 
COMPETITION
 
  The Company faces significant competition with respect to its print
publications, trade shows and conferences and other technology information
services. In its publishing business, the Company principally competes for
advertising and circulation revenue with publishers of other computer
technology publications and also faces broad competition from media companies
that produce general interest magazines, newspapers and online content.
Overall competitive factors include product positioning, editorial quality,
circulation, price and customer service. Competition for advertising dollars
is primarily based on advertising rates, the nature and scope of readership,
reader response to advertisers' products and services and the effectiveness of
sales teams. In its trade show and conference business, the Company competes
with other producers of trade shows and conferences for exhibition space,
exhibitors and attendees, primarily on the basis of the quality of the
conference, its content and organizational efficiency. If the Company is
unable to compete effectively for advertisers, readers, exhibitors and/or
attendees, its financial condition and results of operations could be
adversely affected. See "Business--Competition."
 
CONSOLIDATION OF PRINCIPAL VENDORS; SIGNIFICANT SUPPLIER
 
  The Company's principal vendors include paper suppliers, printers,
fulfillment houses and national newsstand distributors. Each of these
industries is currently experiencing consolidation among their principal
participants. Such consolidation may result in: (i) decreased competition,
which may lead to increased prices; (ii) interruptions and delays in services
provided by such vendors; and (iii) greater dependence on certain vendors.
Such factors could adversely affect the Company's results of operations. One
printing company
 
                                      15
<PAGE>
 
accounted for approximately 50% of the Company's total print publishing
manufacturing expenditures in 1997 for its U.S.-based publications. While the
Company believes there are adequate alternatives available, an interruption or
delay in service from, or the loss of, this printer could have an adverse
effect on the Company. See "Business--Print Publishing--Paper and Printing."
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
 
  One component of the Company's growth strategy is to further expand into
international markets. There are certain risks inherent in doing business in
international markets, such as the uncertainty of product acceptance by
different cultures, the risks of divergent business expectations or
difficulties in establishing joint ventures with foreign partners,
difficulties in staffing and managing multinational operations, currency
fluctuations, state-imposed restrictions on the repatriation of funds and
potentially adverse tax consequences. There can be no assurance that one or
more of such factors will not have an adverse effect on the Company's future
international operations and, consequently, on the Company's financial
condition and results of operations. See "Business --Print Publishing--
International Publications" and "--Trade Shows and Conferences."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of the Offering, the Company expects to have 100 million
shares of Common Stock outstanding (approximately 103.9 million shares if the
U.S. Underwriters' over-allotment option is exercised in full), of which the
25.8 million shares offered hereby and that portion of 100,000 shares which
SOFTBANK Kingston Inc. intends to sell concurrently with the Offering pursuant
to the Registration Statement of which this Prospectus forms a part will be
freely tradeable without restriction by persons other than "affiliates" of the
Company. The remaining shares of Common Stock will be deemed "restricted"
securities within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"), and as such may not be sold in the absence of registration
under the Securities Act or an exemption therefrom, including the exemption
contained in Rule 144 under the Securities Act. The Company and Softbank have
entered into a registration rights agreement in connection with the Offering
which provides Softbank with the right to require the Company to register any
or all of the Common Stock held by Softbank in a public offering pursuant to
the Securities Act and the right to "piggyback" or include Softbank's Common
Stock in any registration of Common Stock made by the Company. No prediction
can be made as to the effect, if any, that future sales of shares of Common
Stock, or the availability of such shares for future sales, will have on the
market price of the shares of Common Stock prevailing from time to time. Sales
of substantial amounts of Common Stock, or the perception that such sales
could occur, could adversely affect prevailing market prices for the Common
Stock, and such a reduction in the market price of the Common Stock could
impair the ability of the Company to raise additional capital through future
public offerings of its equity securities. See "Shares Eligible for Future
Sale."
 
DIVIDEND POLICY; HOLDING COMPANY STRUCTURE
 
  The Company currently intends to retain earnings to finance its operations,
fund future growth and reduce indebtedness and does not anticipate paying
dividends in the foreseeable future. In addition, as a holding company, the
Company's major assets will initially be the shares it holds in its
subsidiaries. Therefore, the Company's ability to pay future dividends and
distributions, if any, to holders of the Common Stock is dependent upon the
receipt of dividends or other payments from its subsidiaries. See "Dividend
Policy."
 
SUBSTANTIAL AND IMMEDIATE DILUTION
 
  The initial public offering price of the Common Stock will be higher than
the book value per share of Common Stock. Accordingly, purchasers in the
Offering will suffer a substantial and immediate dilution of $31.39 in the net
tangible book value per share of Common Stock from the initial public offering
price. See "Dilution."
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the Offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for
the Company's Common Stock will develop or be sustained after
 
                                      16
<PAGE>
 
the Offering. The initial public offering price will be determined by
negotiation between the Company and the representatives of the Underwriters
based upon several factors. See "Underwriters" for a discussion of the factors
to be considered in determining the initial public offering price. The trading
price of the Company's Common Stock could be subject to wide fluctuations in
response to quarterly variations in operating results, expectations of
securities analysts, announcements of new publications or technological
innovations by the Company or its competitors, changes in financial estimates
by securities analysts, the operating and stock price performance of other
companies that investors may deem comparable to the Company and other events
or factors. In addition, the stock market in general has experienced extreme
volatility that often has been unrelated to the operating performance of
particular companies which are traded on the market. These broad market and
industry fluctuations may adversely affect the trading price of the Company's
Common Stock, regardless of the Company's actual operating performance.
 
CERTAIN ANTI-TAKEOVER EFFECTS
 
  Certain provisions of the Company's Certificate of Incorporation and By-Laws
may inhibit changes in control of the Company not approved by the Board of
Directors. The Company will also be afforded the protections of Section 203 of
the Delaware General Corporation Law, which could have similar effects. See
"Description of Capital Stock."

                                  THE COMPANY
 
  The Company believes it is the world's preeminent integrated media and
marketing company focused on computing and Internet-related technology, with
principal platforms in print publishing, trade shows and conferences, online
content, market research and education. The Company's 28 primary U.S. and
international titles, including its joint ventures, and over 50 licensed
publications, total more than 80 publications distributed worldwide, with a
combined circulation of more than eight million primary readers. The Company's
predecessor was founded in 1927 and pioneered the development of special-
interest magazines, including Car and Driver, Popular Photography, Stereo
Review, Boating, Skiing and Modern Bride. The Company also produces the
world's most important trade shows related to computer technology, with over
two million estimated attendees at over 50 trade shows and conferences
worldwide in 1997. The Company's COMDEX/Fall event is the number one ranked
trade show for all industries in the U.S. as measured by total revenue, total
exhibit space and number of attendees. The Company's ZDNet.com Web site is the
leading computing content site and ranked the number one Web site in 1997 in
the category of news, information and entertainment, as measured by visitors
per month. The Company's other media and marketing platforms include market
research, education and the publication of computer-related newsletters,
training manuals and materials.
 
  The Company's principal executive offices are located at One Park Avenue,
New York, New York 10016 and its telephone number is (212) 503-3500.
 
RELATIONSHIP WITH SOFTBANK
 
  The Company is an indirect subsidiary of SOFTBANK Corp., which, as of
December 31, 1997, was 50.2% owned by Mr. Masayoshi Son, its President,
including 43.4% directly held by his 99% owned holding company, MAC. Softbank
is a leading provider of information and distribution services as
infrastructure for the digital information industry. Softbank is Japan's
leading distributor of computer software as well as a leading publisher of
Japanese computer technology publications. It also is an 80% owner of Kingston
Technology Company ("Kingston"), one of the world's largest independent
providers of computer memory modules; a founder and co-owner of Japan Sky
Broadcasting Co., Ltd. ("JSkyB"), a digital satellite broadcasting venture in
Japan; a shareholder, directly or through its investment fund affiliates, in
over 50 network and computer-related venture businesses in the digital
information industry; and a 29.4% owner of Yahoo! Inc.
 
  Upon the completion of the Reorganization, Softbank will own approximately
74.2% of the outstanding shares of Common Stock (71.4% if the U.S.
Underwriters' overallotment is exercised in full). The Company and Softbank
have entered into certain agreements governing various interim and ongoing
relationships between Softbank and the Company, including certain licensing
and management agreements relating to publications, trade shows, ZDTV and
ZDNet. See "Certain Transactions."
 
  In addition, Softbank has given the Company an undertaking that, as long as
it owns 40% of the voting stock of the Company and can elect a majority of the
Board of Directors, it will not expand operations involving (x) publishing
information on computing and Internet-related technology through the media of
print, CD-ROM/DVD, Internet and television, or (y) producing trade shows,
conferences, exhibitions and similar events primarily related to computing and
Internet-related technology outside Japan in competition with the Company
without the prior approval of the Company's management directors after
consulting with the Company's independent directors.
 
  This undertaking does not preclude investments by investment funds managed
by Softbank. Softbank manages certain venture capital funds which invest in,
among other things, computer and Internet-related companies. These funds may
be able to co-invest with the Company or compete with the Company with respect
to new investments. Softbank may develop new funds in the future, which funds
may compete with the Company for investment opportunities. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest" and "Certain Transactions."
 
                                      18
<PAGE>
 
  In order to expand its media platforms, the Company has entered into a
license and services agreement with MAC to develop ZDTV, a 24-hour cable
television channel and integrated Web site focused exclusively on computers,
technology and the Internet. ZDTV is indirectly owned by MAC, but as part of
this license and services agreement MAC has granted the Company an option
exercisable through December 31, 1998 to purchase all of MAC's interest in
ZDTV for an amount equal to MAC's investment plus 10% per annum for the period
of its investment. Pursuant to the license and services agreement, the Company
has agreed to fund ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. Such advances bear interest at the 30-day LIBOR rate plus .50%. ZDTV's
cash requirements are expected to be approximately $54 million in 1998. The
Company's cumulative advances in respect of ZDTV, which totaled $14.4 million
net of $10.1 million in repayments through December 31, 1997, will be repaid
concurrently with the Reorganization. The Company has not yet determined
whether it will exercise its option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon securing sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Company. ZDTV is not included in the
Company's results of operations. See "Certain Transactions."
 
                                      19
<PAGE>
 
                              THE REORGANIZATION
 
  The businesses to be conducted by the Company were acquired in a series of
acquisitions and internal reorganizations undertaken by Softbank. See "The
Company--Relationship with Softbank." The Company's principal business
operations are as follows:
 
    (i) the computer technology publishing operations of Ziff-Davis
  Publishing Company ("ZD Pubco"), which Softbank acquired in February 1996
  for $1.8 billion in cash and subsequently renamed Ziff-Davis Inc.;
 
    (ii) the COMDEX computer-related trade show operations ("COMDEX"), which
  Softbank acquired in April 1995 for $803 million in cash and renamed
  SOFTBANK COMDEX Inc. ("SB COMDEX"); and
 
    (iii) the computer and network-related trade show operations of Ziff-
  Davis Exposition and Conference Company ("ZD Expos"), which Softbank
  acquired in December 1994 for $127 million in cash and subsequently renamed
  SOFTBANK Forums Inc. ("SB Forums").
   
  Concurrently with the ZD Pubco and ZD Expos acquisitions described above,
MAC purchased certain operations and assets of these companies for $302
million and $75 million, respectively. The MAC Assets consist of certain
international consumer and Internet publications, international trade shows
and the ZDNet business, most of which were still under development. The MAC
Assets and related operations have been managed by ZDI and ZDCF since their
acquisition by MAC. As part of the Reorganization discussed below, the MAC
Assets, except for those that have been discontinued, have been or will be
acquired by the Company at a purchase price that does not exceed fair market
value. A portion of the MAC Assets was acquired by the Company on October 31,
1997 for $100 million, and the balance will be sold to the Company
concurrently with the Offerings. See "Use of Proceeds."     
   
  In October 1997, Softbank decided to combine the businesses of ZDI, SB
COMDEX and SB Forums. SB Forums and SB COMDEX were merged as of December 31,
1997, with the surviving corporation named ZDCF. In order to complete the
combination and establish the Company as a separate public company,
concurrently with the sale of the Company's Common Stock offered hereby, ZDI
and ZDCF will be contributed to the Company in exchange for 74.2% of the
Company's Common Stock, and approximately $928 million of the Company's
obligations to Softbank will be converted to equity at the initial public
offering price. The amount of intercompany indebtedness to be converted to
equity is comprised of the obligations due to Softbank as of December 31,
1997, except those repaid with borrowings under the Credit Facility and the
proceeds of the Notes Offering and a $94.2 million note which matures on
February 28, 2009. Assuming an initial public offering price of $15.50 per
share, the value of the capitalized intercompany indebtedness would have been
equivalent to 59.8 million shares of Common Stock. In addition, the Company
will receive approximately $10 million of fixed assets from Kingston in
exchange for $10 million of shares of the Company's Common Stock (valued at
the initial public offering price), which assets will be subsequently leased
back to Kingston.     
 
  As part of the Reorganization, the Company will: (i) issue 25.8 million
shares of its Common Stock in the Offering; (ii) sell $250 million aggregate
principal amount of its    % Senior Subordinated Notes due 2008 in the Notes
Offering; and (iii) enter into the $1.35 billion Credit Facility and borrow
$1.25 billion thereunder. The Company will use the net proceeds from the
Offerings and the Credit Facility to (i) pay $270 million to MAC, representing
the purchase price for the remaining MAC Assets, and (ii) repay approximately
$1.589 billion of obligations to Softbank (including the Company's liability
to Softbank with respect to the $100 million purchase price for the initial
portion of the MAC Assets, net of the approximately $42 million of balances
due from MAC in connection with funding for the MAC Assets and ZDTV through
December 31, 1997), which payment will eliminate all except $94.2 million of
the remaining intercompany indebtedness as of December 31, 1997. The Company
has obtained a commitment letter from The Bank of New York, Morgan Stanley
Senior Funding, DLJ Capital Funding and The Chase Manhattan Bank to provide
such Credit Facility.
 
  Unless the context otherwise indicates, references herein to the
"Reorganization" include all of the transactions described above. The
Offerings will be conditioned upon the completion of all such transactions
comprising the Reorganization, which shall be deemed to occur simultaneously.

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the Common Stock and the
Notes are estimated to be $377.5 million ($434.5 million if the U.S.
Underwriters' over-allotment option is exercised in full) and $241.3 million,
respectively, after deducting underwriting discounts and commissions and
estimated offering expenses payable by the Company. The Company intends to use
the proceeds from the Offerings and approximately $1.25 billion in borrowings
under the Credit Facility, to fund the approximately $270 million purchase
price of the balance of the MAC Assets (see "Risk Factors--Risks Relating to
the Reorganization") and repay approximately $1.589 billion of intercompany
obligations.

                                DIVIDEND POLICY
 
  The Company currently intends to retain all of its earnings following the
Offering in order to finance its operations, repay indebtedness and fund
future growth and, accordingly, does not expect to pay any dividends for the
foreseeable future. The Board of Directors will review this dividend policy
from time to time in light of the conditions then existing, including the
Company's financial condition, results of operations, capital requirements,
restrictions, if any, contained in financing or other agreements binding upon
the Company, and such other factors as the Board of Directors deems relevant.
The Credit Facility and provisions of the Notes contain certain limitations on
the payment of dividends. See "Risk Factors--Dividend Policy; Holding Company
Structure" and "Description of Certain Indebtedness--Notes" and "--Credit
Facility."

                                   DILUTION
 
  As of December 31, 1997 the pro forma net tangible book value of the Company
was a deficit of $1.97 billion or $26.50 per share of Common Stock. Pro forma
net tangible book value per share is determined by dividing the tangible net
worth of the Company (total assets less intangible assets and total
liabilities) by the aggregate number of shares of Common Stock outstanding,
assuming the Reorganization had taken place on January 1, 1997. After giving
effect to the sale of the 25.8 million shares of Common Stock offered hereby
(at an assumed initial offering price of $15.50 per share, the mid point of
the range set forth on the cover page of this Prospectus) and the application
of the net proceeds therefrom, pro forma net tangible book value of the
Company as of December 31, 1997 would have been a deficit of approximately
$1.59 billion, or $15.89 per share. This represents an immediate increase in
pro forma net tangible book value of $10.61 per share to Softbank, the current
stockholder of ZDI and ZDCF, and an immediate dilution in pro forma net
tangible book value of $31.39 per share to purchasers of Common Stock in the
Offering. The following table illustrates the per share dilution in pro forma
net tangible book value to new investors:

(1) Dilution is determined by subtracting pro forma net tangible book value
    per share after the Offering from the initial public offering price per
    share.
 
  The following table summarizes, on a pro forma basis, as of December 31,
1997, the number of shares of Common Stock purchased from the Company, the
total consideration paid (or to be paid) and the average price per share paid
(or to be paid) by the Company's existing stockholder and by new investors
purchasing shares of Common Stock in the Offering, based on an assumed initial
public offering price of $15.50 per share, before deducting estimated offering
expenses and underwriting discounts and commissions.

(1) Historical Combined Financial and Other Data of ZDI has been presented for
    all periods prior to its acquisition by Softbank on February 29, 1996 as
    it represents the Company's principal operations.
(2) Reflects operations of SB Forums for the year and COMDEX from the date of
    acquisition by Softbank on April 1, 1995.
(3) Reflects operations of SB Forums and COMDEX for the year and ZDI from the
    date of acquisition by Softbank on February 29, 1996.
(4) For the years ended December 31, 1993 and 1994, the operations of ZDI were
    conducted through various partnerships. Accordingly, no income taxes have
    been provided.
(5) No historical earnings per share or share data are presented as the
    Company does not consider such data meaningful.
(6) For purposes of the computations, earnings before fixed charges consist of
    income/(loss) before income taxes adjusted for equity earnings/losses as
    appropriate, plus fixed charges. Fixed charges are defined as interest
    expense plus that portion of rental expense which is deemed to be
    representative of the interest factor. For the year ended December 31,
    1995 and the two-month period ended February 28, 1996, ZDI's earnings were
    insufficient to cover fixed charges by $36,859 and $6,760, respectively.
    For the years ended December 31, 1996 and 1997, ZDI and ZDCF's earnings
    were insufficient to cover fixed charges by $26,598 and $74,520,
    respectively.

statements of ZDI and ZDCF and has been prepared to illustrate the effects of
the Reorganization and the other transactions described below.
 
  The Unaudited Pro Forma Combined Statement of Operations for the year ended
December 31, 1997 gives effect to the Reorganization as if it had occurred as
of January 1, 1997. The Unaudited Pro Forma Combined Balance Sheet as of
December 31, 1997 has been prepared as if the Reorganization had occurred on
that date. See "The Reorganization."
 
  The Pro Forma Financial Information is not necessarily indicative of the
actual results of operations or financial position of the Company at December
31, 1997 and does not purport to represent the Company's results of operations
for future periods or its future financial position.
 
  The Pro Forma Financial Information should be read in conjunction with the
Historical Combined Financial Statements of ZDI and ZDCF and notes thereto
which are included elsewhere in this Prospectus. In management's opinion, the
Pro Forma Financial Information includes all adjustments necessary to reflect
the effects of the Reorganization and other transactions described below.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  The Company operates in two business segments: (i) publishing and (ii) trade
shows and conferences. The Company believes it is the world's preeminent
integrated media and marketing company focused on computing and Internet-
related technology, with principal platforms in print publishing, trade shows
and conferences, online content, market research and education. The Company's
28 primary U.S. and international titles, including its joint ventures, and
over 50 licensed publications, total more than 80 publications distributed
worldwide, with a combined circulation of more than eight million primary
readers. The Company also produces the world's most important trade shows
related to computer technology, with over two million estimated attendees at
over 50 trade shows and conferences worldwide in 1997. The Company's
COMDEX/Fall event is the number one ranked trade show for all industries in
the U.S. as measured by total revenue, total exhibit space and number of
attendees. The Company's ZDNet.com Web site is the leading computing content
site and ranked the number one Web site in 1997 in the category of news,
information and entertainment, as measured by visitors per month. The
Company's other media and marketing platforms include market research,
education and the publication of computer-related newsletters, training
manuals and materials.
 
  The Company had net revenue of $1.154 billion for 1997. A substantial
portion of the Company's revenue is derived from the sale of advertising,
which in 1997 accounted for 51.9% of total revenue. No single advertiser has
comprised more than 3% of the Company's advertising revenue during any of the
last three years. However, the Company's top 20 advertisers accounted for
32.1% of total advertising revenue for 1997.
 
  In the publishing segment, the Company's principal sources of revenue are
advertising (67.3% of 1997 total publishing revenue), circulation (17.4%) and
other (15.3%). Circulation comprises both paid subscriptions (10.8%) and
newsstand sales (6.6%) while other includes educational and training materials
(5.4%) and market research studies (6.2%) with the balance primarily
consisting of royalties, reprints and other miscellaneous sales. In the trade
shows and conferences segment, revenue is derived from two principal sources:
sale of exhibit space (64.8% of 1997 total segment revenue) and attendee
conference and seminar fees (14.9%). Unlike many trade show producers, the
Company derives a significant portion of its trade show revenue from other
sources (20.3%), including advertising in show-related publications,
billboards, banners, fees from managing customer-sponsored events and other
show-related activities. The Company believes these other sources will
continue to be an important growth area, particularly for its content-focused
events.
 
  In the publishing business, the principal components of the Company's
production costs are raw materials, printing and distribution, which
represented 34.6%, 37.5% and 26.7%, respectively, of total 1997 publishing
production expenses. The Company's principal raw material is paper. Paper
supply and prices are subject to volatility and may be significantly affected
by many factors, including market and economic conditions. See "Risk Factors--
Risks Associated with Fluctuations in Paper and Postage Costs" and "--
Inflation and Change in Paper Prices." The principal components of production
costs within the trade shows and conferences business are the costs of renting
and preparing the facilities to hold the events (33.6%), direct mail and the
related costs for promotion of the events (33.2%) and program development and
presentation costs (11.3%).
 
  The other principal operating costs for the Company are selling, general and
administrative expenses, including editorial costs. Included in these costs
are salaries, sales commissions and benefits (49.8%) along with marketing and
promotion expenses related to advertising and circulation (18.8%).
 
  The Company's revenue and profitability are influenced by a number of
external factors, including the volume of new technology product
introductions, the amount and allocation of marketing expenditure by the
Company's clients, the extent to which sellers elect to advertise using print
and online media or participate in trade shows and conferences, changes in
paper prices, availability of appropriate venues for its largest trade shows
and conferences and competition among computer technology marketers (including
print publishers, producers of trade shows and providers of other technology
information services). Accordingly, the Company may experience fluctuations in
revenue from period to period. Many of the Company's large customers
 
                                      30
<PAGE>
 
concentrate their advertising expenditures around major new product launches.
Marketing expenditures by technology companies can also be affected by factors
affecting the computer industry generally, including pricing pressures and
temporary surpluses of inventory. Revenue and profitability are also
influenced by product mix and the timing and frequency of the Company's new
product launches and launches in new markets, as well as by acquisitions. New
publications generally require several years to achieve profitability and upon
achieving initial profitability, often have lower margins than more
established publications. The launch of new publications, trade shows and
services are funded with cash flow from operations and are expensed as
incurred. Accordingly, the Company's revenue from year to year may be affected
by the number and timing of new product launches. If the Company concludes
that a new publication, trade show or service will not achieve certain
milestones with regard to revenues, profitability and cash flow within a
reasonable period of time, management may discontinue such publication, trade
show or service or merge it into another existing publication, trade show or
service. See "Risk Factors--New Product Risks."
   
  The Company's taxable income for 1998 will be greater than the pre-tax
income reported in its financial statements. The difference results from
certain items which are non-deductible for income taxes, primarily losses
generated from the MAC Assets prior to transfer to the Company and non-
deductible goodwill amortization (see Note 8 to the Combined Financial
Statements of ZDI and ZDCF). Consequently, the Company's effective tax rate
for the year will be significantly in excess of the statutory rates. In
accordance with generally accepted accounting principles, the Company will
record income taxes on a quarterly basis at the estimated annual effective tax
rate. As a result, the Company expects to record income tax benefits in
quarters where pre-tax losses are incurred and income tax expense in periods
where pre-tax profits are generated.     
   
  Historically, the financing requirements of the Company have been funded
through intercompany loans and advances, totaling $2.5 billion at December 31,
1997, of which $126 million was current. As a result of the Reorganization,
the Company's intercompany debt owed to Softbank will be reduced to $94.2
million. Such indebtedness bears interest at 9.9% and matures in February
2009. Concurrently with the Offering, the Company will enter into the $1.35
billion Credit Facility and borrow $1.25 billion thereunder. See "--Liquidity
and Capital Resources."     
 
PRESENTATION OF FINANCIAL INFORMATION
 
  ZD Inc. was incorporated on February 4, 1998. Concurrent with the completion
of the Offerings, all of the common stock of ZDI and ZDCF, the Company's
principal operating subsidiaries, will be contributed to the Company.
 
  These subsidiaries were acquired in a series of acquisitions and internal
reorganizations undertaken by the Company's principal stockholder, Softbank.
In December 1994, Softbank acquired SB Forums for $127 million in cash. The
acquisition was accounted for using the purchase method of accounting and
accordingly, the results of operations of SB Forums are included in the
Combined Financial Statements of ZDI and ZDCF for 1995, 1996 and 1997.
 
  In April 1995, SOFTBANK acquired SB COMDEX for $803 million in cash, plus
transaction costs. The acquisition was accounted for using the purchase method
of accounting and accordingly, SB COMDEX's results are included in the
Combined Financial Statements since the date of acquisition. As of December
31, 1997, SB Forums and SB COMDEX were merged, with the surviving corporation
named ZD Comdex and Forums (ZDCF).
 
  In February 1996, Softbank acquired Ziff-Davis Publishing Company
(subsequently renamed Ziff-Davis Inc.) for $1.8 billion in cash. The
acquisition of ZDI has been accounted for using the purchase method of
accounting and accordingly, the results of ZDI are included in the Combined
Financial Statements since the date of acquisition. ZDI's results of
operations for periods prior to the date of acquisition are set forth in the
ZDI Financial Statements included elsewhere in this Prospectus.
 
                                      31
<PAGE>
 
  In connection with the acquisition of SB Forums and ZDI described above,
MAC, Softbank's largest shareholder, purchased certain operations and assets
of these companies for $75 million and $302 million, respectively. The MAC
Assets consist of certain international publications, consumer and Internet
publications, international trade shows and the ZDNet business, most of which
were still under development. As part of the Reorganization, the MAC Assets,
except for those which have been discontinued, have been or will be sold to
the Company. The acquisition of the MAC Assets has been accounted for in a
manner similar to a pooling of interests and is reflected in the Combined
Financial Statements of ZDI and ZDCF for all periods presented.
 
  Due to the acquisition of ZDI on February 29, 1996 and the resulting
revaluation of assets and liabilities and the change in the Company's capital
structure, the historical financial statements of ZDI and ZDCF are not
directly comparable. The table below presents the Company's pro forma results
for 1996 and 1995 as if ZDI and ZDCF had been under common control since
January 1, 1995. The results of SB COMDEX are included since April 1, 1995.
The combined results for 1995 and 1996 were derived by combining the statement
of operations for ZDI for the year ended December 31, 1995 and for the period
January 1, 1996 to February 28, 1996 with the combined statement of operations
for ZDI and ZDCF for the years ended 1995 and 1996. In addition, the purchase
accounting adjustments related to the 1996 acquisition of ZDI have been
reflected as of January 1, 1995 resulting in pro forma amortization, interest
and income tax provision adjustments. Such adjustments are further described
in note (a) to the table set forth below under "--Results of Operations." No
pro forma adjustments have been made related to the acquisition of SB COMDEX
as such adjustments are not material. Although such combination is not in
accordance with generally accepted accounting principles, management believes
the combined statements present the most meaningful basis of comparison.
Intercompany transactions for those periods were immaterial. The financial
information presented herein may not necessarily reflect the results of
operations which would have occurred had the Company been a stand-alone
entity.

- --------
(a) The acquisition of ZDI on February 29, 1996 gave rise to different bases
    of accounting for the period after the acquisition versus the period prior
    to the acquisition. This is primarily due to a purchase price which
    exceeded the book value of the assets acquired, financed by a higher level
    of both debt and equity as compared to the pre-acquisition capital
    structure. The amounts indicated above assume that the acquisition of ZDI
    took place on January 1, 1995; therefore, depreciation and amortization,
    interest expense and net loss have been increased (decreased) by
    approximately $6,386, $824 and $10,383, respectively, for 1996 and
    $38,312, $(3,484) and $46,759, respectively, for 1995.
(b) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. EBITDA is not intended to
    represent cash flows from operations and should not be considered as an
    alternative to net income as an indicator of the Company's operating
    performance or to cash flows as a measure of liquidity. The Company
    believes that EBITDA is a standard measure commonly reported and widely
    used by analysts, investors and other interested parties in the publishing
    and media industries.
 
THREE MONTHS ENDED MARCH 31, 1998 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1997 (UNAUDITED)
 
  For the first quarter of 1998, the Company will report revenue of $228.1
million compared to $224.9 million for the first quarter of 1997. Revenue from
publishing operations will decline approximately 4.1% primarily due to the
absence of $12.8 million of revenue from Macuser and MacWeek magazines, which
were transferred in October 1997 to a 50/50 joint venture with another
publishing company and are no longer consolidated in the Company's results.
The publishing segment will also report lower advertising revenue from its
business publications principally as a result of factors affecting the
computer technology industry generally, including slowing demand for computer
products, fewer new product launches, pricing pressures, vendor market share
shifts and excess PC inventories in distribution channels. This decline will
be largely offset by increased
 
                                      33
<PAGE>
 
advertising sales in the Company's Internet business and consumer
publications. More than offsetting the decline in publishing revenue will be
an increase of 77% in revenue from the Company's tradeshows and conferences
operations, primarily the result of earlier production of two events in the
first quarter of 1998 that had been held in the second quarter of 1997.
   
  The Company will report a loss from operations of $24 million for the first
quarter of 1998 as compared with a loss from operations of $15.6 million for
the first quarter of 1997. Reported EBITDA for the first quarter of 1998 will
be $15.1 million as compared to $25.5 million for the comparable period of
1997. The unfavorable variances are primarily due to the lower level of
advertising in business publications, which have higher profit margins than
consumer publications or the Internet business, coupled with approximately
$3.2 million of one-time costs for office relocations and $1.4 million of
expenses incurred in launching two new publications.     
 
  As indicated below under "Seasonality," the first quarter accounted for
approximately 19.4% and 19.5% of the Company's revenue in 1996 on a pro forma
basis and 1997, respectively, and approximately 12.0% and 9.4% of the
Company's EBITDA for the respective years.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED WITH PRO FORMA YEAR ENDED DECEMBER 31,
1996
 
 Revenue
 
  Revenue increased by $73.2 million or 6.8% from $1,080.6 million in 1996 to
$1,153.8 million in 1997.
 
  Revenue from publishing grew by $50.5 million or 6.2% from $815.7 million to
$866.2 million. Approximately $22 million was due to inclusion of a full year
of results for the electronic gaming publications acquired in mid-1996 and two
publications launched in late 1996. Revenue from Internet services increased
$13.5 million or 71.9% due to higher advertising volume attributable to the
Company's growing presence on the Internet. Increases in advertising rates,
generally ranging between 3% and 10%, and a 5.1% increase in advertising pages
contributed $11.5 million. Revenue from international operations, which
generated 10.2% of the segment's revenue, decreased by $6.6 million due to the
strengthening of the U.S. dollar relative to the major European currencies.
Continued growth from new educational product launches and sales of market
research studies accounted for the balance of the revenue growth.
 
  Revenue from trade shows and conferences increased $22.6 million or 8.5%
from $264.9 million to $287.5 million. Approximately $15 million of the
increase was due to 11 new trade show launches, including revenue from
ancillary show-related sources. The balance of revenue growth was due to
higher exhibitor rates charged at the major events, partly offset by a decline
in revenue from COMDEX/Spring and certain U.K. events.
 
 Cost of production
 
  Production costs increased $22.6 million or 7.5% from $302.6 million to
$325.2 million.
 
  Publishing production costs increased $10.4 million or 4.8% from $215.3
million in 1996 to $225.7 million. Costs related to new launches and volume-
related growth increased approximately $20 million but were partly offset by
approximately $10 million of lower paper costs.
 
  The costs of producing trade shows and conferences increased $12.2 million
or 14.0% from $87.3 million to $99.5 million primarily as a result of costs
related to new events launched in 1997.
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses increased $35.7 million or 6.8%
from $528.6 million to $564.3 million. The increase was due to the addition of
employees to support base business volume growth and launches of new products
and services. Results included a one-time $6.0 million charge for the
consolidation and restructuring of the trade shows and conferences business
which was announced in the fourth quarter of 1997. Costs for the publishing
segment rose 4.2% while those for the trade shows and conferences segment rose
22.1% due to the number of new launches and the one-time restructuring charge.
 
                                      34
<PAGE>
 
 Depreciation and amortization
 
  Total depreciation and amortization decreased $6.3 million to $154.9 million
in 1997. The reduction in depreciation and amortization expense was a result
of certain assets being fully depreciated in 1996.
 
 Interest expense, net
 
  Net interest expense increased $54.9 million or 40.5% to $190.4 million in
1997 due to interest on an additional $900 million of intercompany
indebtedness to Softbank incurred to finance a return of capital.
 
 Other non-operating income, net
 
  Other non-operating income/expense primarily reflects the Company's equity
share of earnings and losses from joint ventures and fees earned from
management of trade shows and conferences not produced by the Company. Income
increased $2.6 million from $6.1 million in 1996 to $8.7 million or 42.6%
reflecting growth in fees from managed events and reduced losses from joint
ventures.
 
 Income Taxes
 
  The 1997 combined income tax benefit of $1.3 million compares to a pro forma
income tax provision of $25.7 million in 1996. The improvement in the tax
provision is due to a higher pre-tax loss giving rise to a tax benefit. The
difference between the 1997 and 1996 effective tax rates and the federal
statutory tax rate of 35.0% is primarily due to non-recognition of tax losses
generated by the MAC Assets ($56.9 million and $77.2 million in 1997 and 1996,
respectively), non-deductible goodwill amortization ($10.2 million and $8.6
million, respectively) and state and local income taxes. In addition, the 1996
tax provision increased approximately $3.2 million as a result of pro forma
adjustments related to the ZDI acquisition.
 
 Net loss
 
  As a result of the changes described above, net loss for the period
increased $4.2 million or 6.2% from $67.0 million to $71.2 million.
 
 EBITDA
 
  EBITDA for 1997 was $272.9 million, an increase of $17.5 million or 6.8%
from the $255.4 million generated in 1996. The increase was due to higher
revenue and management fee income, net of higher production costs and selling,
general and administrative expenses. The ratio of EBITDA to revenue remained
relatively constant at 23.7% for 1997 compared to the 1996 margin of 23.6%.
Excluding the one-time charge related to the consolidation and restructuring
of the trade shows and conferences business, the 1997 ratio would have been
24.2%.
 
PRO FORMA YEAR ENDED DECEMBER 31, 1996 COMPARED WITH PRO FORMA YEAR ENDED
DECEMBER 31, 1995
 
 Revenue
 
  Revenue increased by $108.9 million or 11.2% from $971.7 million in 1995 to
$1,080.6 million in 1996.
 
  Revenue from publishing grew by $46.7 million or 6.1% from $769.0 million to
$815.7 million. Higher overall advertising rates combined with a 12.4% growth
in advertising pages contributed 47.5% of the revenue increase while the mid-
1996 acquisition of several electronic gaming publications accounted for 28.5%
of the increase. New educational product launches and growth in sales of
market research studies accounted for the balance of revenue growth. Internet
revenue was slightly below the prior year due to the transition from a
business based on membership and subscription fees to one which is supported
primarily by advertising.
 
  Revenue from trade shows and conferences increased $62.2 million or 30.7%
from $202.7 million to $264.9 million. The launch of new international trade
shows accounted for 36.7% of the growth while the introduction of customized
events contributed 19.8%. The balance of the increase was due to growth in
exhibitor square footage and rates at the Company's major U.S. shows.
 
                                      35
<PAGE>
 
 Cost of production
 
  Production costs increased $40.2 million or 15.3% from $262.4 million to
$302.6 million.
 
  Publishing production costs increased $21.6 million or 11.2% from $193.7
million to $215.3 million, primarily due to volume-related growth and higher
paper costs. Approximately 31.5% of the increase was attributed to costs for
the magazines acquired mid-year while increased frequencies on certain
publications and a full year of costs for publications launched in late 1995
accounted for 18.1% of the increase.
 
  The costs of producing trade shows and conferences increased $18.6 million
or 27.0% from $68.8 million to $87.4 million. The increase was driven by the
cost of new product launches as well as higher direct marketing and facility-
related fees for the major U.S. events.
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses rose $53.6 million or 11.3%
from $475.0 million to $528.6 million. This increase reflects the addition of
employees to support growth in the base business along with the launches of
new products and services. Costs for the publishing segment rose 5.8% while
those for the trade shows and conferences segment rose 61.6%, reflecting a
higher level of new launches and the absence of COMDEX related expenses for
the first three months of 1995 (COMDEX was acquired April 1, 1995).
 
 Depreciation and amortization
 
  Total depreciation and amortization of $161.3 million increased $7.1 million
from $154.2 million in 1995 primarily due to the inclusion of a full year's
depreciation and amortization relating to SB COMDEX, which was acquired April
1, 1995.
 
 Interest expense, net
 
  Net interest expense increased $2.4 million or 1.8% on a pro forma basis due
to higher average debt levels in 1996.
 
 Other non-operating income, net
 
  Income increased to $6.1 million compared to $.8 million in 1995 due to the
growth in fees from managed events along with reduced losses from joint
ventures.
 
 Income Taxes
 
  The combined income tax provision of $25.7 million compares to an income tax
provision of $9.6 million in 1995. The unfavorable variance in income taxes
and the difference in the 1996 and 1995 effective tax rates from the federal
statutory tax rate of 35% is primarily attributable to non-recognition of tax
losses generated by the MAC Assets ($77.2 million in 1996) and non-deductible
goodwill amortization ($8.6 million in 1996). In addition, the tax effects of
the 1996 and 1995 pro forma adjustments relating to the ZDI acquisition were a
$3.2 million and $11.9 million increase in tax provision, respectively.
 
 Net Loss
 
  As a result of the changes described above, net loss for the period
increased $5.2 million or 8.4% from $61.8 million to $67.0 million.
 
 EBITDA
 
  EBITDA for 1996 was $255.4 million, an increase of $20.3 million or 8.7%
from the $235.1 million generated in 1995. The increase was due to higher
revenue and management fee income, net of higher production costs and selling,
general and administrative expenses. The cost of new product launches caused
the growth rate of expenses to exceed the revenue growth rate and, as a
result, the ratio of EBITDA to revenue of 23.6% decreased slightly from 24.2%
for 1995.

LIQUIDITY AND CAPITAL RESOURCES
 
  Historically, the financing requirements of the Company have been funded
through intercompany loans and advances.
   
  As a result of the Reorganization, the Company's intercompany debt owed to
Softbank will be reduced to $94.2 million. Such indebtedness bears interest at
9.9% and matures in February 2009. Concurrently with the Offering, the Company
intends to issue and sell $250 million aggregate principal amount of Notes. In
addition, the Company will enter into the $1.35 billion Credit Facility, and
borrow $1.25 billion thereunder, to provide additional funds for the repayment
of intercompany debt to Softbank and to provide for the Company's working
capital requirements. It is expected that Softbank will apply a portion of the
amounts received by it to the Reorganization, among other things, to prepay
all amounts outstanding under a credit facility (under which the Company is a
guarantor) and terminate the commitments thereunder. See "Certain
Transactions--Certain Related Party Transactions."     
   
  The Credit Facility will consist of a seven year $500 million reducing
revolving credit facility (with $400 million drawn at closing), a seven year
$450 million term loan and an eight year $400 million term loan. There will be
no scheduled reductions in the revolving credit commitment or amortization
under the term loan until September 2000. The Company has obtained a
commitment letter from The Bank of New York, Morgan Stanley Senior Funding,
DLJ Capital Funding and The Chase Manhattan Bank to provide such Credit
Facility. The consummation of each of the Offerings and the borrowings under
the Credit Facility are conditioned upon, and will occur simultaneously with,
the consummation of the others.     
 
  Cash and cash equivalents were $30.3 million and $29.9 million at December
31, 1997 and 1996, respectively. The balance increased $.4 million due to the
factors discussed below:
 
  Cash (used) provided by operating activities was $(3.4) million and $65.7
million for the years ended December 31, 1997 and 1996, respectively. The
decrease from 1996 to 1997 was the result of higher interest expense and final
payment of long-term incentives to management established in connection with
the sale of ZDI in 1994.
 
  For the year ended December 31, 1997, the Company used $44.2 million in cash
for investing activities, principally $30.2 million in capital expenditures.
The majority of these expenditures were for computer equipment and leasehold
improvements. The Company believes that future capital expenditures associated
with new office space will be approximately $35 million in 1998 and $25
million in 1999 (net of tenant improvement credits). Cash used for investing
activities on a pro forma basis for 1996 was $66.8 million principally due to
capital expenditures of $22 million and the acquisition of Sendai Publishing
Group for $28 million.
 
  For the year ended December 31, 1997, the Company generated $47.9 million in
cash from financing activities, principally $66.6 million of capital
contributed by MAC to fund the operating losses of the MAC Assets, net of a
$21.4 million repayment of intercompany indebtedness. Pro forma cash flow from
financing activities for the year 1996 was $6.8 million, primarily from
capital contributions of $14.8 million from Softbank offset by a dividend of
$8.0 million.
 
  The Company believes that, based on its current level of operations and
anticipated growth, the Company's ability to generate cash, together with
other available sources of funds including available cash on hand at December
31, 1997, of $30.3 million, will be adequate over the next 12 months to make
required payments of principal and interest on the Company's indebtedness, to
fund anticipated capital expenditures and future working capital requirements.
However, actual capital requirements may change, particularly as a result of
any acquisitions the Company may pursue. The ability of the Company to meet
its debt service obligations and reduce its total debt will depend upon the
future performance of the Company.
 
  The Company has entered into a license and services agreement with MAC to
develop ZDTV. ZDTV is indirectly owned by MAC, but as part of this license and
services agreement MAC has granted the Company an option exercisable through
December 31, 1998 to purchase all of MAC's interest in ZDTV for an amount
equal
 
                                      37
<PAGE>
 
to MAC's investment plus 10% per annum for the period of its investment.
Pursuant to the license and services agreement, the Company has agreed to fund
ZDTV's operations on behalf of MAC through unsecured advances which, for
approved levels of expenditure, are to be reimbursed by MAC. Such advances
bear interest at the 30-day LIBOR rate plus .50%. ZDTV's cash requirements are
expected to be approximately $54 million in 1998. The Company's cumulative
advances in respect of ZDTV, which totaled $14.4 million net of $10.1 million
in repayments through December 31, 1997, will be repaid concurrently with the
Reorganization. The Company has not yet determined whether it will exercise
its option to purchase MAC's interest in ZDTV. Any such purchase will depend
upon securing sufficient cable carriage, which may include entering into a
joint venture or other co-ownership arrangement, including an arrangement with
a third party cable system operator which will provide carriage and also
assume a portion of the ongoing cash requirements on terms that are acceptable
to the Company. ZDTV is not included in the Company's results of operations.
In the event that the Company acquires a controlling interest in ZDTV from
MAC, such acquisition would be accounted for as a pooling transaction; in the
event that the Company acquires a non-controlling interest, such acquisition
would be accounted for under the equity method. See "Certain Transactions."
 
SEASONALITY
 
  Historically, the Company's business has been seasonal as a significant
portion of the trade shows and conferences segment revenue has occurred in the
second and fourth quarters. In addition, the Company's publishing segment has
generated higher revenue in the second and fourth quarters. The following
table sets forth certain unaudited quarterly combined statements of operations
data for each of the eight quarters in the period ended December 31, 1997. In
the opinion of the Company's management, this unaudited information has been
prepared on a basis consistent with the audited Combined Financial Statements
of ZDI and ZDCF appearing elsewhere in this Prospectus (with the exception of
the March 31, 1996 data which has been prepared on the basis described in
Presentation of Financial Information above) and includes all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the information set forth therein when read in conjunction with the Combined
Financial Statements and related notes thereto. The operating results for any
quarter are not necessarily indicative of results for any future period.

INFLATION AND CHANGES IN PAPER PRICES
 
  The Company continually assesses the impact of inflation and changes in
paper prices. The Company generally enters into contracts for the purchase of
paper which adjust the price on a quarterly basis. Paper prices began to rise
in 1994, rose significantly in 1995 and 1996 then decreased in 1997.
Management expects paper prices to increase again in 1998. The Company will
continue to monitor the impact of inflation and paper prices and will consider
these matters in setting its pricing policies.
 
                                      38
<PAGE>
 
  The Company frequently reviews its purchasing and manufacturing processes
for opportunities to reduce costs and mitigate the impact of paper price and
postage rate increases (such as purchasing lighter-grade paper stock or, when
paper prices are at cyclical lows, increasing paper inventory or entering into
longer term contracts with suppliers). However, the Company has not entered,
and does not currently plan to enter, into long-term forward price or option
contracts for paper. See "Risk Factors--Risks Associated with Fluctuations in
Paper and Postage Costs" and "Business--Print Publishing--Paper and Printing."
 
YEAR 2000 ISSUES
 
  The Company uses a number of computer software programs and operating
systems, including applications for its internal electronic communications
network and for various administrative and billing functions. The Company has
assessed the scope of the Company's risks related to problems these computer
systems may have in processing date information related to the year 2000 and
believes such risks are not significant.
 
  The Company has identified all of its significant internal software
applications which contain source codes that may be unable to appropriately
interpret the year 2000 and has already begun to modify or replace those
applications. The estimated costs to modify or replace these applications are
not material to the Company.
 
  In addition, the Company has inquired of its vendors and business partners
about their progress in identifying and addressing problems related to the
year 2000. All major vendors with whom the Company exchanges electronic
information or on whose internal software applications the Company may be
dependent, have committed to the Company that plans are in place to be
compliant before processing of information related to calendar year 2000 would
be required. Although no assurance can be given that all of these third party
systems will be year 2000 compliant, the Company believes that risk is not
significant.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997, will
require the Company to disclose, in financial statement format, all non-owner
changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments, certain minimum pension liabilities and
unrealized gains and losses on securities available for sale. This statement
is effective for fiscal years beginning after December 15, 1997 and requires
presentation of prior period financial statements for comparability purposes.
 
  SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and
interim financial reports. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
Generally, financial information is required to be reported on the basis that
is used internally for evaluating segment performance and deciding how to
allocate resources to segments.
 
  SFAS No. 132, "Employer's Disclosure about Pensions and Other Postretirement
Benefits," is effective for the year ended December 31, 1998. This statement
revises the disclosure requirements for employers' pension and other retiree
benefits.
 
  The Company expects to adopt the above statements beginning with its 1998
financial statements.
 
FORWARD-LOOKING STATEMENTS

                                   INDUSTRY
 
  Technology is widely recognized as one of the largest and fastest growing
sectors of the United States economy. The market for technology goods and
services is undergoing rapid expansion, largely fueled by: (i) increased
integration of computers into the workplace and home; (ii) shortened product
life cycles; and (iii) increased use of the Internet. The demand for computer
technology to enhance productivity as well as the increasing number of
applications in the areas of education, entertainment and communications has
dramatically increased the number of computers in use. The number of personal
computers in use worldwide has doubled from 150 million in 1995 to over 300
million in 1997, significantly broadening the consumer and business markets
for computer technology. In addition, rapid technological advances have
shortened product life cycles; for example, the estimated marketable product
life of a PC has decreased from five years in 1981 to less than six months
today. The Internet has also become a widely accepted information tool as
demonstrated by the proliferation of users, with 68 million adults in the U.S.
having used the Internet by year-end 1997, up from just five million in 1994,
and the sharp increase in the number of commercial Web sites worldwide, from
30,000 in 1995 to approximately 400,000 in 1997.
 
  For buyers and users of computer technology products, these factors have
increased the demand for objective, up-to-date information and analysis. For
sellers of such products, these factors have increased their need to
communicate a wide range of information regarding their products and services,
from advertising designed to increase sales to education designed to improve
end-user satisfaction and build brand loyalty. Computer technology-focused
media enable sellers to communicate their message effectively by targeting a
focused customer base. As a result of the broadening of the consumer base, as
well as the favorable demographics of this base, computer technology
publications and other media are becoming increasingly attractive as a
platform for consumer product advertising.
 
COMPUTER TECHNOLOGY PRINT PUBLICATIONS MARKET
 
  In 1996, advertising revenue in computer-oriented print publications
totalled $1.3 billion. In 1997, advertising revenue in computer-oriented
publications grew by 11.2% while the advertising market as a whole grew by
8.3% in the first ten months (the latest period for which data is available)
as compared to the same period in the prior year. Growth in advertising and
circulation revenue for computer-oriented publications has outpaced the
publishing industry in general, growing 10.4% a year from 1994 to 1997, versus
6.3% a year for all periodicals.
 
COMPUTER TECHNOLOGY TRADE SHOWS
 
  A trade show can be described as a face-to-face version of a print
publication. Trade show attendees, like readers of print publications, are
presented with product advertisements in the form of exhibits and "editorial"
content in the form of conferences and other ancillary forums. Producers of
trade shows and conferences generate revenue from exhibit space sales,
advertising and conference and general attendance fees. Trade shows and
conferences allow sellers to conduct a large volume of face-to-face sales
presentations to qualified buyers in a short period of time. Professional
attendees include hardware and software manufacturers and developers, sales
and distribution personnel and large volume end-users. Industry leaders such
as Microsoft Corporation, Intel Corporation and Cisco Systems, Inc. have
consistently used these events to promote the launch of important products in
order to reach top-ranking decision-makers in the computer technology
industry.
 
  Trade shows are becoming an increasingly important part of the marketing
strategy for information technology vendors. A recent study noted that
companies consider trade shows one of the most effective mediums for
generating and closing sales, second only to direct selling. Exhibit space
revenues from North American computer-product trade shows were approximately
$573 million in 1997. In 1997, exhibit square footage rose 28% at such shows,
the number of exhibiting firms increased 20% and attendance rose 28%.

ONLINE AND OTHER TECHNOLOGY INFORMATION SERVICES
 
  The proliferation of Web sites and the growing number of users combine to
make the Internet an increasingly significant advertising and brand-building
vehicle. The Internet enables marketers to deliver targeted messages as a
result of the ability to track consumer behavior and immediately convert
advertising responses into commercial transactions. The advertising-based
business model for online services, which is similar to print and television
media, involves the payment to Internet content and service providers of
advertising fees based primarily on the demographics and purchasing habits of
the audience and on the number and positioning of advertisements delivered.
The market for advertising on the Internet was approximately $597 million in
1997, a 152.6% increase from 1996. The computer technology industry has been
one of the leading advertisers on the Internet, comprising 35% of all
advertising dollars for the twelve months ended September 30, 1997. Web sites
focused on computing content provide yet another forum for sellers of computer
technology to deliver targeted product information and advertising to a
premium customer base. The Company expects that the Internet market, like the
publications market, will continue to broaden and gain appeal as a platform
for consumer product advertising as well.

                                   BUSINESS
 
  The Company believes it is the world's preeminent integrated media and
marketing company focused on computing and Internet-related technology, with
principal platforms in print publishing, trade shows and conferences, online
content, market research and education. The Company provides global technology
companies with marketing strategies for reaching key decision-makers. The
Company is the successor to Ziff-Davis Publishing Company, which pioneered the
development of special-interest magazines; Ziff-Davis Exposition and
Conference Company; and the COMDEX computer and network-related trade show
operations of Interface Group-Nevada, Inc.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the
top three computer magazines in the U.S. and are among the top 25 U.S.
magazines, each as measured by total revenue in 1996 (the latest year for
which data is available). The Company also produces the world's most important
trade shows serving vendors, resellers, buyers and users of computer
technology, including COMDEX/Fall, the largest trade show in the U.S. in 1997.
The Company's ZDNet.com Web site is the leading computing content site and
ranked the number one Web site in 1997 in the category of news, information
and entertainment, as measured by visitors per month.
 
  The Company's 28 primary U.S. and international titles, including its joint
ventures, and over 50 licensed publications, total more than 80 publications
distributed worldwide, with a combined circulation of over eight million
primary readers. In 1997, Ziff-Davis was the largest technology publisher in
the U.S. in terms of total magazine revenue. In that same year, Ziff-Davis
accounted for 36.8% of all advertising and circulation dollars spent in
computer periodicals, with at least 50% more total magazine revenue than its
closest competitor. The Company's publications include PC Magazine, the
largest circulation computer magazine in the world, Computer Shopper, the
leading magazine targeted at direct buyers of computers (along with its Web-
based companion, Netbuyer), Computer Life, a monthly magazine for home
computing enthusiasts, and Family PC, a magazine specifically targeted to
households with children. ZD Labs, its computer testing facility, enables the
Company to provide reliable and authoritative product evaluations to a
sophisticated audience of brand-specifiers and decision-makers in both the
business and consumer markets. The preeminence of the Company's publications
among readers and advertisers is based on its comprehensive market and product
coverage, the quality of its editorial content and the influence of its
readership.
 
  In 1997, the Company produced over 50 trade shows and conferences worldwide
with over two million estimated attendees. The Company's COMDEX/Fall event is
the number one ranked trade show for all industries in the U.S. as measured by
total revenue, total exhibit space and number of attendees.
 
  The Company's other media and marketing platforms include online content,
market research, education and the publication of computer-related newsletters
and training manuals. In addition, the Company and MAC have developed ZDTV,
the first 24-hour cable television channel and integrated Web site focused
exclusively on computers, technology and the Internet, which is expected to be
launched in the first half of 1998. The Company has an option to purchase ZDTV
from MAC on or before December 31, 1998. See "--Television."
 
  The Company developed certain international consumer and Internet
publications, international trade shows and the ZDNet business under the
ownership of MAC. As a result of the Reorganization, these businesses have
been or will be purchased from MAC. See "The Reorganization."
 
  The Company's Ziff-Davis Media Network integrates the Company's marketing
activities into one cohesive resource for its largest customers. Originally
established to provide discounts for advertisers buying across two or more
magazine titles, the Media Network has been expanded to allow marketers to
reach their various target buyers through any combination of the Company's
media and marketing platforms.
 
  The Company had total revenue of $1.154 billion for 1997. The Company's
revenue is primarily derived from advertising sales, which represented 51.9%
of total revenue in 1997. The second largest component of the Company's
revenue is derived from trade shows and conferences, which accounted for 23.5%
of total revenue in
 
                                      42
<PAGE>
 
1997. Circulation revenue, comprised of subscription and newsstand single copy
sales, generated 13.1% of the Company's revenue in 1997 and other revenue
components, including online content, market research and revenue derived from
joint ventures and licenses, contributed 11.5% in 1997.
 
BUSINESS AND OPERATING STRATEGY
 
  The Company's objective is to be the preferred marketing partner to
technology vendors and service providers seeking to reach primary decision-
makers involved in the specification and purchase of their products and
services. Major elements of the Company's strategy include:
 
  Maintain Focus on the Computer and Internet Technology Markets. The Company
believes that its singular focus on the computer and Internet-related
technology markets provides it with substantial growth opportunities as well
as the ability to broaden its expertise in attracting both audiences and
advertisers.
 
  Develop the Most Comprehensive, Objective and Authoritative Content. The
Company strives to produce the most comprehensive, objective and authoritative
editorial content in order to attract category brand-specifiers and decision-
makers to its media platforms. The ability to provide focused audiences with
their specific information needs attracts the leading advertisers and
exhibitors to the Company's products and services.
 
  Build Upon Brand Strength of Existing Media Properties. The Company will
pursue continued growth from its core portfolio of leading brands, such as PC
Magazine, PC Week, COMDEX and ZDNet, by seeking to expand its market share of
audiences and advertisers and enhancing the quality and accessibility of the
content it produces and marketing services it provides. In addition, the
Company will continue to extend its existing brands into other platforms to
offer multiple media presentations of its content.
 
  Continue to Leverage Multiple Media Marketing Platforms. The Company
believes that the scope and depth of its products and services across multiple
media platforms and geographic territories creates growth opportunities
exceeding those that such businesses could achieve independently. Such
opportunities include the leveraging of strong relationships with accounts in
one media platform into other platforms, cross-marketing Ziff-Davis products
and services to the audiences of its different platforms and packaging
integrated marketing products across all platforms for large advertisers. The
Company believes that its ability to offer clients multiple platform marketing
solutions gives it a competitive advantage over single platform providers.
 
  Expand Leadership on the Internet. The Company intends to use its already
significant presence on the Internet and broad experience in publishing to
continue to reach new audiences and increase advertising revenue. In addition,
the Company believes that the large existing audience for ZDNet and its
affiliated sites, together with its publishing experience, gives it a
competitive advantage in identifying, acquiring and developing new products
and services.
 
  Launch New Products and Services. The Company believes that rapid advances
in technology create additional growth opportunities for the launch of new
products and the expansion of its audiences and advertising base. The Company
seeks to be the first to identify new audiences and develop products and
services which respond to their informational needs. Management believes that
the scope of its operations and its experience in launching new products
across multiple media platforms and geographic regions reduce the risks
typically associated with these activities and enable it to more readily
achieve market acceptance for new products and services as compared to other
media companies.
 
  Expand Global Reach. The Company intends to leverage its widely recognized
brands and its experience in multinational operations to expand further into
key overseas markets, focusing on those markets which have size and growth
characteristics that will support its strategy of cross-media operations.
Management intends to further expand internationally through the launch
overseas of proven U.S. properties, joint ventures and licensing arrangements
with local operating partners and through selective acquisitions.
 
  The Company expects to fund its business and operating strategy from
internally generated cash flow from operations, which are estimated to be
sufficient to fund investments as well as the repayment of indebtedness. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

PRINT PUBLISHING
 
  The Company is a leading computer-related magazine publisher, with 28
primary U.S. and international titles, including its joint ventures, and over
50 licensed publications, totaling more than 80 publications distributed
worldwide. In 1997, the Company's publications had combined circulation of
over eight million primary readers worldwide. Approximately 62% of the
Company's total revenue in 1997 was attributable to its print publishing
business. Each of the Company's magazines is designed to appeal to a target
audience of sophisticated customers in the business and consumer markets by
providing high-quality editorial content, often supported by independent
laboratory-based product testing. The Company seeks to maintain and increase
its revenue by introducing current advertisers to new titles, by attracting
new advertisers targeted at the Company's readership and by developing new
reader and advertising categories. Each of the Company's primary publications
has established its own Web site as a complementary delivery platform.
 
  The Company believes its preeminent position in the computer publishing
market is based upon its leading brands in key categories, its ability to
successfully develop new brands for emerging product categories, its strength
in circulation and its ability to expand internationally. Ziff-Davis seeks to
produce the highest quality editorial content; it employs top editors and
columnists supported by laboratory-testing facilities that produce widely
acknowledged authoritative benchmarks for determining product quality. See "--
Editorial, Laboratory Testing and Benchmark Software." In addition to its
leading publications targeted at brand-specifiers and other industry
professionals, the Company has successfully introduced new publications
targeted at emerging sectors, including the consumer market (Family PC,
Computer Life and Computer Gaming World), technology lifestyle (Yahoo!
Internet Life) and Internet professionals (Internet Computing and Inter@ctive
Week). The Company's newsstand strategy focuses on developing strong
relationships with a key distributor and large retail accounts. In order to
offer clients coverage of broad international markets, the Company has adopted
a licensing strategy designed to maximize global reach and maintain content
quality in international publications while reducing cost of entry into new
markets. Depending on the characteristics of a particular market, the Company
may choose to own an international publication, enter into a master license
covering one or more titles, or enter into a joint venture if an attractive
local partner can be identified.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the
top three computer magazines in the U.S. and are among the top 25 U.S.
magazines, each as measured by total revenue in 1996 (the latest year for
which data is available). In 1997, Ziff-Davis was the largest technology
publisher in the U.S. in terms of total magazine revenue. In that same year,
Ziff-Davis accounted for 36.8% of all advertising and circulation dollars
spent in computer periodicals, with at least 50% more total magazine revenue
than its closest competitor. In recent years, advertisements in the Company's
publications have expanded beyond those for computer technology products to
include consumer product advertising, reflecting the desirable demographics of
the Company's readership, as well as the expanding readership of computer
technology publications to a broader consumer market.
 
  The Company's publications include paid-circulation magazines, which
generate revenue from newsstand sales, subscriptions and advertising, and
controlled-circulation publications, which are distributed free of charge to
qualified information technology professionals and generate revenue
principally from the sale of advertising. In addition, the readership of
controlled-circulation publications provides valuable demographic information
to the Company. Most of the current Ziff-Davis publications are either monthly
magazines providing comparative, laboratory-based product reviews or news
weeklies providing product and industry news and analysis; however, the
Company also serves the developing market for lifestyle and entertainment
publications focusing on technology.
 
  The Company's U.S. publications have a total circulation of over six million
primary readers, and the Company had a worldwide circulation of over eight
million primary readers. Its six paid-circulation business magazines
(including one joint venture) accounted for 47.2% of the total paid-
circulation of all computer technology business magazines in the U.S. in 1997.
In 1997, PC Magazine's circulation was greater than that of Business Week,
Fortune or Forbes. With respect to newsstand sales, a critical measure of
magazine vitality, in the first six months of 1997 Ziff-Davis accounted for
47.5% of all computer magazine copies sold, and on average Computer Shopper
had greater newsstand sales than Business Week, Fortune and Forbes combined.

 ZIFF-DAVIS MEDIA NETWORK
 
  The Company's Ziff-Davis Media Network integrates the Company's marketing
activities into one cohesive resource for its largest customers. Originally
established to provide discounts for advertisers buying across two or more
magazine titles, the Media Network has been expanded to allow marketers to
reach their various target buyers through any combination of the Company's
media and marketing platforms. Currently 21 professionals in the Ziff-Davis
Media Network link major advertisers from one platform into other platforms.
 
 EDITORIAL, LABORATORY TESTING AND BENCHMARK SOFTWARE
 
  The Company has invested heavily in its editorial staff and in training and
technology to develop the high level of technical expertise required to
provide quality content on computer technology. It employs over 450 editorial
personnel worldwide, including award-winning editors and experts in their
fields. The Company believes that it provides its consumers with the most
reliable, objective and focused product evaluations and industry news. Because
of the quality and reputation of Ziff-Davis laboratory tests, the Company's
publications are widely regarded as a reliable source of objective product
evaluations. The Company's influence over computer purchasing carries with it
the responsibility to maintain the highest standards of fairness and
objectivity in its product reviews. To ensure this impartiality, Ziff-Davis
has instituted policies governing separation of editorial functions from
advertising sales functions and restricting trading in securities of
technology-related companies by its journalists.
 
  The Company is committed to laboratory-based product testing as an integral
part of its editorial mission. In 1997, the Company spent over $10 million in
laboratory testing. Testers from many of the Company's different publications
work with the ZD Labs staff to provide comprehensive, objective test results
that can assist readers and users of Ziff-Davis publications and other
content-based services in making buying decisions. In addition to the core ZD
Labs staff, Ziff-Davis publications such as PC Magazine, PC Week, Computer
Shopper and PC Computing maintain their own staff and/or testing space at ZD
Labs as well as at their own locations. The ZD Labs testing facility provides
space for testing hundreds of products and systems. One of its newest
facilities is an Internet/Intranet lab dedicated to testing Web servers and
other Internet products. In its domestic lab facilities, the Company employs
120 technicians, enabling it to test thousands of products each year and
conduct large-scale tests that effectively simulate corporate installations.
The Company believes ZD Labs gives it a competitive advantage in terms of
staffing, equipment and access to the technology necessary to evaluate
products.
 
  ZD Labs produces the core, publicly available and widely distributed
benchmark software that Ziff-Davis publications use worldwide to measure the
performance of PCs, Macintosh systems and servers. The Company's benchmarks
have become industry standards among major buyers of computer and Internet-
related technology.
 
 SOURCES OF PRINT PUBLISHING REVENUE
 
  Advertising Sales. The Company's advertising strategy for its publishing
business is based on helping customers maximize the return on their
advertising investment. Advertising sales accounted for 78.4% of the Company's
total print publishing revenue for 1997. Ziff-Davis has historically invested
in comprehensive research to better understand the computer technology market
and the positions of its different publications. The Ziff-Davis sales
philosophy is to encourage its sales force to adopt the role of marketing
consultant, using Ziff-Davis market research tools, such as the Company's
InternetTrack and BrandTrack services, to provide clients with information on
overall industry trends as opposed to more limited sales presentations
focusing on individual publications. As of December 31, 1997, Ziff-Davis
employed over 250 salespeople, sales managers and sales executives and over
325 sales support staff in its publishing segment to provide customer service,
research, promotional support and value-added programs for advertisers.
 
  Circulation. Ziff-Davis maintains centralized circulation operations which
enable the Company to capitalize on its successful strategies and practices
across all publications on a timely basis. The Company strives
 
                                      46
<PAGE>
 
to increase its readership by building relationships with distributors,
retailers and subscribers. Revenue from circulation of the Company's paid-
circulation magazines accounted for 18.4% of the Company's total print
publishing revenue in 1997. This was comprised of subscription sales (10.1% of
total revenue in 1997 and 10.5% in 1996) and newsstand sales (8.1% in each of
1997 and 1996). The Company's publications have a total circulation of over
eight million primary readers worldwide.
 
  The Company's newsstand strategy focuses on developing strong relationships
with a key distributor and large retail accounts. Ziff-Davis recently entered
into a newsstand distribution arrangement in the U.S. with Warner Publishers
Services ("Warner"), a division of Time Warner Inc., which covers the
Company's entire line of paid-circulation magazines. As of January 1998, the
Company became Warner's principal supplier of computer technology
publications. In addition, the Company has preferred distribution arrangements
with large retailers including WalMart, Barnes & Noble, Staples and Office
Max. These arrangements include special magazine displays featuring Ziff-Davis
brand products which increase the prominence of the Company's publications and
strengthen its brand identity. With respect to newsstand sales, a critical
measure of magazine vitality, Ziff-Davis publications accounted for 47.5% of
all computer magazine copies sold in the first six months of 1997.
 
  The Company's subscription strategy is to maintain a highly focused
readership in order to provide the most effective affinity between advertisers
and readers. The Company believes that this strategy increases subscriber
loyalty and renewal rates and allows the Company to provide advertisers with
access to a precisely focused target audience. The Company's six paid-
circulation business magazines (including one joint venture) accounted for
47.2% of the total paid circulation of all computer technology business
magazines in the U.S. in 1996.
 
  Licensing and Joint Ventures. The Company has adopted a licensing strategy
designed to maximize global reach and maintain content quality in
international publications while reducing the cost of entry into new markets.
In markets where the Company believes that the opportunity is significant
relative to the cost of entry, the Company may operate through wholly-owned
publishing companies. Through subsidiaries, the Company currently has
publishing operations in France, the United Kingdom and Germany. In other
markets, the Company has opted to enter into licensing arrangements with local
publishing companies, and currently has over 50 licensed publications
worldwide. The Company's licenses are generally three to five year agreements
that provide for a minimum annual royalty against a percentage of revenue. The
Company also operates through a number of joint venture companies with
partners, including joint ventures with International Data Group, Inc. ("IDG")
and an affiliate of The Walt Disney Company ("Disney") in the U.S. and a
venture with Richina Media Holdings and other local agencies in China. The
Company is currently negotiating with an affiliate of Disney to buy its
interest in the Family PC joint venture.
 
 U.S. PUBLICATIONS
 
  Business Magazines. In the U.S. market, the Company publishes ten computer
publications directed to business buyers, including six paid-circulation
magazines and four controlled-circulation weeklies or bi-weeklies. Each
publication produces authoritative, independent guidance that the Company
believes is generally considered to be the primary product resource in its
market segment. Two of these titles, Macworld and MacWeek, are dedicated to
the Apple Macintosh market and are published by Mac Publishing L.L.C., a joint
venture between the Company and IDG.
 
    PC Magazine provides corporate buyers of computer technology with
  comprehensive laboratory-based comparative reviews of PC hardware, software
  and networking products, with a focus on technical specifications. With a
  paid circulation of more than 1.18 million, PC Magazine is the largest
  circulation computer magazine in the world, accounting for 35.4% of all
  computer advertising revenue in directly competitive U.S. publications in
  1997. PC Magazine has expanded its editorial material into other media,
  including a Web publication, PC Magazine Online, and a CD ROM-based
  multimedia companion magazine, PC Magazine Extra, which has a paid
  circulation of over 75,000. PC Magazine also produces two newsstand-only
  specials: Your New PC, which supplies buying advice for less sophisticated
  computer buyers, and InternetUser, which focuses on reviews of Internet
  products.

three year agreements, with quarterly pricing adjustments, and are renewable
on a staggered basis. Most agreements contain pricing clauses that seek to
ensure the most competitive pricing on a quarter to quarter basis. The
Company's main paper suppliers for its U.S. publications are Bowater,
Champion, Consolidated, Fraser and UPM, which provided 12%, 33%, 15%, 12% and
12%, respectively, of the Company's paper supply in 1997 as measured by
tonnage. Printing companies that the Company has relationships with include
R.R. Donnelley, Brown, Quadgraphics and Quebecor. Approximately 50% of the

TRADE SHOWS AND CONFERENCES
 
  The Company is the leading producer of trade shows, conferences and
customized marketing and educational programs for the computer industry in the
U.S. Approximately 25% of the Company's total revenue in 1997 was attributable
to its trade show and conference business which includes the industry-wide
COMDEX events, other trade shows and conferences focused on specific segments
of the computer technology industry, and customized events designed to meet
the marketing needs of specific clients. In 1997, the Company produced over 50
trade shows and conferences, 18 of which were held in North America.
 
  The COMDEX/Fall event has been held for 18 years and is the number one
ranked trade show for all industries in the U.S. as measured by total revenue,
total exhibit space and number of attendees. In 1997, the Company estimates
that over two million people attended Company trade shows and conferences
worldwide. In addition to COMDEX/Fall, held annually in Las Vegas, the Company

computer industry, while the Seybold Seminars focus on publishing and graphic
communications. In addition, the Company will produce the following segment-
focused trade shows in 1998: (i) WINDOWS WORLD in conjunction with Microsoft
Corporation; (ii) EXPO COMM, servicing the worldwide telecommunications
industry; (iii) CommUnity, for the emerging corporate integrated data, voice
and video segments; (iv) COMDEX/Enterprise, focusing on solutions for the
large corporate information technology infrastructures; (v) Java Internet
Business Expo, sponsored by Sun Microsystems, Inc. and focusing on the full
range of Java technology for information technology professionals; (vi)
Service and Support Expo, focusing on technology for help desk and information
technology support services; and (vii) Learning Technology, focusing on
applying technology to education and training. The Company's customized
conferences are designed to meet the marketing needs of a specific client. For
example, the Company produced the Java One series of conferences for Sun
Microsystems, Inc. which were designed to introduce Java software to the
developer community.
 
  Attendees at the Company's trade shows and conferences cover a wide range of
participants from the computer industry, including manufacturers,
distributors, dealers, retailers, value-added and other resellers and large
corporate end-users. Each event includes an extensive conference program,
which provides a forum for the exchange and dissemination of information
germane to the particular event's focus. In addition, each event has one or
more "keynote" sessions with speakers drawn from computer industry leaders.
The Company estimates that in 1997 over 5,000 companies participated as
exhibitors in its trade shows and conferences and over 8,000 industry experts,
analysts and consultants spoke at its conference programs.

 SOURCES OF TRADE SHOW AND CONFERENCE REVENUE
 
  In 1997, exhibitor space fees accounted for 64.8% of the Company's total
trade show and conference revenue. The Company believes most trade show
producers receive virtually all of their revenue from the sale of exhibitor
space fees. The Company has actively sought to increase its revenue from other
sources, including attendee fees, which accounted for 35.2% of all trade show
and conference revenue in 1997.
 
  At each trade show, all exhibitors pay the same price per square foot of
booth space, regardless of the exhibit hall they select or the location or
size of their booth within a given hall. Typically, a majority of each trade
show's exhibitors commit to booth space during that year's show for the next
year's show. The Company encourages this commitment through a booth selection
procedure that grants priority based upon a seniority system. Annual renewal
is required for exhibitors to maintain their seniority. Exhibitors pay for
space in two or three installments, the last of which is usually due six
months prior to the upcoming event.
 
  In 1997, attendee fees accounted for 14.9% of the Company's trade show and
conference revenue, primarily from N+I and Seybold events. Most COMDEX
attendees come as the invited guests of exhibiting companies. The Company
provides exhibiting companies with a supply of complimentary admission
tickets, which are generally given to customers and key prospects. This helps
exhibitors ensure that their best customers and prospects will attend.
 
  The Company's trade show and conference advertising revenue is derived
principally from five products: (i) a daily newspaper distributed during the
show; (ii) the Program Exhibits Guide; (iii) the Preview, a newspaper
published and distributed to pre-registrants and certain prior year attendees
in advance of the show; (iv) advertising billboards and banners; and (v)
ancillary exhibitor logo products which are sold to exhibitors to increase
booth traffic and name recognition.
 
  The Company also maintains a continuously updated database containing the
names and certain demographic information on its over two million attendees.
This database is rented to direct mail users on a fee-per-use basis.
 
 COMDEX
 
  COMDEX trade shows cover a broad range of new technologies at every stage in
their development and evolution--from introduction to commercial maturity.
Many of the most significant computer product launches over the past 18 years
occurred at COMDEX, including the launch of the IBM PC, Lotus 1-2-3, Windows
3.1 and DVD.
 
  COMDEX/Fall is a five-day trade show held annually in November in Las Vegas.
In 1997 COMDEX/Fall had over 1,750 exhibiting companies occupying more than
1,350,000 net square feet of exhibit space and more than 200,000 attendees.
COMDEX/Spring, which was launched in 1981, is a smaller version of the fall
event. In 1997, it was held in Atlanta and had more than 600 exhibiting
companies and over 100,000 attendees. In April 1998, COMDEX/Spring will be
held in Chicago. For the last six years, the Company, in cooperation with
Microsoft Corporation, has produced a WINDOWS WORLD trade show concurrently
with COMDEX/Spring.
 
  In 1993, the Company began launching additional COMDEX events in order to
capitalize on the international recognition of the COMDEX brand name. The 1998
schedule includes other COMDEX events in Miami, Toronto, Vancouver, Montreal,
Mexico City, Monterrey (Mexico), Buenos Aires, Sao Paulo, Rio de Janeiro,
London, Paris, Tokyo, Seoul, New Delhi, Beijing, Singapore and Cairo.
 
 NETWORLD + INTEROP
 
  N+I is the largest of the Company's segment-focused trade shows and is the
leading show for professionals in the rapidly growing field of computer
networking. N+I places strong emphasis on the quality of its conference
programs and, in recent years, has become a leading educational forum for the
Internet and enterprise computing
 
                                      52
<PAGE>
 
communities. The largest N+I event is held annually in Las Vegas in May. Each
N+I trade show features InteropNet, a live, multi-platform network that
interconnects exhibitors to one another and to the Internet. In 1997, the N+I
Las Vegas event had over 600 exhibiting companies occupying more than 400,000
net square feet of exhibit space and more than 55,000 attendees. The N+I
Atlanta event, held in October each year, is only slightly smaller in all
categories. The 1998 schedule of N+I events includes seven shows in six
countries.
 
 SEYBOLD SEMINARS
 
  The Company's Seybold Seminars are segment-focused trade shows and are a
leading information and education provider for traditional and new media
publishing industries. These shows focus on the latest technologies and
products, design tools and desktop applications. The largest of the Seybold
series is held annually each September in San Francisco. In 1997, this Seybold
show had over 300 exhibiting companies occupying more than 140,000 net square
feet of exhibit space and more than 38,000 attendees. Other Seybold events are
held in New York and Tokyo.
 
 OTHER EVENTS
 
  The Company also produces EXPO COMM, a series of worldwide trade shows
focusing on the telecommunications, wireless and telephony segments of the
information technology marketplace. The Company purchased a 50% interest in
the series from EXPO COMM's founder, E.J. Krause & Associates, Inc., in 1996.
EXPO COMM events are held in Chicago, Moscow, Beijing, Buenos Aires, Sao
Paulo, Mexico City, Monterrey (Mexico) and Tokyo. WINDOWS WORLD trade shows
are held in cooperation with Microsoft Corporation concurrently with the
Company's COMDEX events in Chicago, Mexico City and Toronto. These events
showcase the latest Windows-based applications and solutions.
 
  The Company also produces Learning Technology trade shows for professionals
focused on learning and helping others to learn to use technology, held in
Atlanta and Los Angeles, and Object World trade shows focused on the
commercial and practical aspects of applying object technology and distributed
computing in today's business environment, held in San Francisco, Boston,
London, Frankfurt and Tokyo.
 
INTERNET
 
  The Company maintains a number of Web sites related to its publications,
trade shows and conferences and other media platforms. The Company's ZDNet.com
Web site is the leading computing content site and the number one Web site in
the category of news, information and entertainment, in each case as measured
by visitors per month in 1997, ranking it higher than Web sites produced by
Time Warner Inc. (Pathfinder.com), Disney (Disney.com) and ESPN
(Sportzone.com). The Company estimates that the ZDNet Web site serves more
than 100 million pages each month to more than five million visitors. It has
over one million registered users and over 2.5 million e-mail recipients per
month. ZDNet has successfully attracted new audiences in addition to
established computer enthusiasts, as is evidenced by the fact that 64% of
ZDNet users do not regularly read any computer technology publications. ZDNet
seeks to be the most comprehensive site for quality content about computing.
 
  ZDNet has its own staff of over 100 editors, designers and technology
experts who create and develop a wide range of content, including current and
in-depth news, product reviews, investor information, shareware library,
online shopping, training, forums and chat areas. ZDNet coordinates and
collaborates on content development with the Company's other publications and
businesses and is fully integrated with the Company's individual Web sites.
ZDNet includes Netbuyer, a leading Web site devoted to computer retailing.
Softbank is a majority owner of Gamespot, a leading Web site for gaming
information, including reviews, demo downloads and other content. Softbank's
interest in Gamespot will be contributed to the Company concurrently with the
Reorganization. Over 80% of the content on ZDNet is original, with the
remainder supplied by the Company's print publications.
 
                                      53
<PAGE>
 
  The Company has a number of arrangements with leading Web sites and product
manufacturers to increase traffic and thereby advertising revenue to ZDNet.
ZDNet is the preferred computer and technology content-provider for leading
Internet sites and products, including Yahoo!, Excite, MSNBC and Pointcast, as
well as for leading Internet service providers such as Mindspring and AT&T's
World Net, each of which provides a direct link to ZDNet. ZDNet also has
arrangements with original equipment manufacturers, such as Compaq Computer
Corp. and Gateway 2000, Inc., whereby ZDNet is an automatic bookmark in the
Web browsers included on such computers.
 
  The Company distributes localized versions of ZDNet in Germany as ZDNet
Deutschland, in France as ZDNet France and in the United Kingdom as ZDNet UK.
Localized versions of ZDNet are also distributed by licensees in Italy,
Russia, Japan, China, Taiwan, Australia and Latin America.
 
TELEVISION
 
  In order to expand its media platforms, the Company has entered into a
license and services agreement with MAC to develop ZDTV, which is expected to
be launched in the first half of 1998. ZDTV will be the first 24-hour cable
television channel and integrated Web site focused exclusively on computers,
technology and the Internet. ZDTV will target a wide range of viewers,
including computer and technology enthusiasts, computer gaming enthusiasts,
business people, teens, families and other viewers with a sustained interest
in computers, technology and the Internet. Programs are expected to include
educational features, product evaluations, gaming tips and strategies, current
events and other entertainment. ZDTV will also feature live interactive
programming allowing viewers to participate through simultaneous Web
programming on ZDTV.com.
 
  ZDTV is indirectly owned by MAC, but as part of the license and services
agreement, MAC has granted the Company an option exercisable through December
31, 1998 to purchase all of MAC's interest in ZDTV for an amount equal to
MAC's investment plus 10.0% per annum for the period of its investment.
Pursuant to the licence and services agreement, the Company has agreed to fund
ZDTV's operations on behalf of MAC through unsecured advances which, for
approved levels of expenditure, are to be reimbursed by MAC. Such advances
bear interest at the 30-day LIBOR rate plus .50%. ZDTV's cash requirements are
expected to be approximately $54 million in 1998. The Company's cumulative
advances in respect of ZDTV, which totaled approximately $14.4 million net of
$10.1 million in repayments through December 31, 1997, will be repaid
concurrently with the Reorganization. The Company has not yet determined
whether it will exercise its option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon access to sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Company. ZDTV is not included in the
Company's results of operations. See "Certain Transactions."
 
  ZD Television Productions, which is also indirectly owned by MAC, creates
customized programming for ZDTV and third parties. The Company's option to
purchase ZDTV from MAC also includes the option to purchase ZD Television
Productions. Its productions have included the regional Emmy award-winning
"The Site" with MSNBC and "21st Century Home" with Home & Garden Television.
See "Certain Transactions."
 
EDUCATION
 
  The Company is an independent publisher of computer training products and
services for end-users and advanced technology professionals. Its products and
services include Internet-based training, computer-based training, instructor-
led courseware and customization tools. The Company believes that its
education offerings extend the Company's reach and brand reputation while
permitting the Company to attract and retain customers.
 
  The Company is a source of software-specific newsletters and technology
information, with more than 50 titles, a family of CD-ROM products and an
interactive Web site. Generally published monthly, the titles include time-
saving tips and techniques on products such as Windows 95, Novel NetWare,
Visual Basic, Word, Excel, Microsoft Office, PhotoShop and Windows NT, in
addition to several programming and operating systems journals. The Company's
informational Web site provides instant access to a library of back issues,
reviews, online links and chats with authors.
 
                                      54
<PAGE>
 
  Through ZD University, an Internet-based educational program, the Company
provided training to more than 37,000 paid subscribers in 1997, an increase of
100% from 1996. The ZD University Web site is closely integrated with ZDNet,
helping to ensure that customers of one service are exposed to other Company
services.
 
  Through the Help Desk Institute and the Support Services Professionals
Association, the Company provides training programs and publications for
hardware and software support service professionals. The Company also
publishes Inside Technology Training, which reaches 40,000 information
technology and training managers, and other software support professionals. In
addition, the Company owns and operates a single-site training center that
specializes in applications, programming and certification training for
Microsoft, Novell and Lotus, and the Training Center Alliance, which provides
qualifying training center customers with enhanced marketing support and
referral capabilities worldwide.
 
MARKET RESEARCH
 
  The Company's market research division develops, analyzes and compiles a
wide variety of information on computer technology issues ranging from
technical aspects of current usage to trends in decision making. The Computer
Intelligence ("CI") unit focuses on information concerning installed and
planned technology hardware and software purchases, and is a leading source in
North America and Europe of fact-based information concerning hardware and
software needs for the computer and communications industries. CI is an
important part of the Company's effort to be a single source marketing
solution, as it can provide the Company's marketing customers with important
information to identify their target customers. CI's databases are built from
more than 30,000 telephone interviews per month and contain data on installed
and planned computer and communications products and services at over 400,000
business sites in the U.S., Canada and eight European countries, according to
Company estimates. CI assists the Company's clients in identifying and
targeting their customers by tracking current activity and market share in the
business, home and reseller channels. Customers use CI's services to make
important marketing decisions.
 
  The Company also identifies and analyzes trends in the decision making
process for consumers of computer technology. This type of information helps
to identify criteria other than technical product specifications that are used
in product selection. The Company's market research division also consolidates
information obtained in each of the databases maintained by the Company's
other operating divisions, so that each Ziff-Davis division can offer the
Company's clients a wide range of information to meet their marketing needs
across multiple platforms.
 
  The Company publishes Microprocessor Report, a leading technical publication
for the microprocessor industry. It also produces Microprocessor Forum, the
industry's leading conference for the introduction of new high-performance
microprocessors, and PC Tech Forum, events which together attract more than
1,000 paid attendees and provide information on trends and markets.
 
COMPETITION
 
  The Company competes with a wide range of companies for each of the products
and services it provides. Although such competition is significant and is
likely to increase in the future, the Company believes it has a greater
breadth of product and service offerings than any of its competitors.
 
  The magazine publishing business is highly competitive. The Company faces
broad competition, not only from other technology publishers, but from other
media companies as well, including business, news and general interest
magazine publishers. Other principal computer and technology publishers in the
United States include IDG, CMP Media Inc., The McGraw-Hill Companies and
Imagine Publishing, each of which produces publications that directly compete
with one or more of the Company's publications. The Company also competes with
various computer and technology publishers in the international markets in
which it conducts business. A
 
                                      55
<PAGE>
 
publishing company's success depends upon a number of factors, such as
editorial quality, product positioning and price. Competitive factors for
advertising sales include quality of readership, circulation, reader response
and advertising rates. The Company believes its publications effectively
compete in the marketplace on the basis of each of these factors.
 
  The Company also faces competition in its trade show and conference
business, primarily from several significant trade show management companies.
These include Miller Freeman, Mecklermedia Corporation and IDG. The Company
believes its trade shows compete in the marketplace on the basis of quality of
conference content, organizational efficiency, and quality and number of
exhibitors and attendees.
 
  The Internet media business is highly competitive. An increasing number of
companies are developing online content and services for delivery on the World
Wide Web in order to compete for audiences and the advertising dollars that
are currently being directed to the Internet. ZDNet competes with other
technology-related online content sites such as c|net, CMPnet, and IDGnet.
 
  The Company's market research division faces competition from numerous
market research companies, including International Data Corporation, Gartner
Group's Dataquest and IntelliQuest. Database providers such as Information
Resource Group and Dun & Bradstreet provide additional competition.
 
  The Company's education division competes with a variety of education
providers, including vendor-supplied training materials and traditional
classroom-based computer training.
 
  ZDTV is expected to be the first 24-hour cable television channel and
integrated Web site focused on computer technology and the Internet, and as
such it is not expected to face direct competition in the near future. It
will, however, face competition from a variety of general and special interest
television programs. The market for television programming is highly
competitive, with many programming producers competing both for channel
carriage and for advertiser and audience market share.
 
TRADEMARKS
 
  The Company has developed strong brand awareness for its principal
publications, trade shows and other products and services. Accordingly, the
Company considers its trademarks, copyrights, trade secrets and similar
intellectual property as critical to its success and relies on trademark,
copyright and trade secrets laws, as well as licensing and confidentiality
agreements, to protect its intellectual property rights. The Company generally
registers its material trademarks in the United States and in certain other
key countries in which these trademarks are used. Effective trademark,
copyright and trade secret protection may not be available in every country in
which the Company's publications and services are available.
 
  The Company may be subject to claims of alleged infringement by it or its
licensees of trademarks and other intellectual property rights of third
parties from time to time in the ordinary course of business. The Company does
not believe there are any such legal proceedings or claims that are likely to
have, individually or in the aggregate, a material adverse effect on the
Company's business, financial condition or results of operations.
 
FACILITIES
 
  The Company's world headquarters are located in New York and the Company has
over 50 editorial, production and sales offices and computer labs in many
other cities in the United States and around the world. The Company's other
principal offices are located in the Boston and San Francisco metropolitan
areas. The Company does not own real property that is material to its business
and leases all but one of its offices from third parties. The Company believes
that its properties, taken as a whole, are in good operating condition and are
suitable and adequate for the Company's current business operations, and that
suitable additional or alternative space, including space available under
lease options, will be available at commercially reasonable terms for future
expansion.

EMPLOYEES
 
  As of December 31, 1997, the Company had a total of 3,698 employees. Of
these employees, 1,160 were engaged in U.S. magazine publishing activities,
350 in international publishing activities, 728 in trade shows and
conferences, 197 in Internet-related activities, 414 in education activities,
486 in market research and 363 in central administrative services. None of the
Company's U.S. employees is represented by a labor union. The Company
considers its relationships with its employees to be satisfactory.
 
LEGAL PROCEEDINGS
   
  The Company has been named as a defendant in an action, filed on April 17,
1998, in the Supreme Court of the State of New York, by minority shareholders
of SOFTBANK Interactive Marketing Inc. ("SIM"), formerly an indirect
subsidiary of Softbank. The complaint alleges, among other things, that SBH,
SIM's majority shareholder, acting with the Company and two of its senior
officers and directors who were directors of SIM (and who are also named as
defendants), had conflicts of interest between SIM and other Softbank
investments (including investments in the Company) and failed to act in the
best interests of SIM and the minority shareholders by taking actions which
benefitted the Company. The complaint states claims based on common law fraud,
breach of fiduciary duty and aiding and abetting theories and seeks in excess
of $200 million in damages. The investment in SIM was solely by SBH, which
intends a vigorous defense on behalf of itself and the Company.     
 
  There are no other legal proceedings to which the Company is a party, other
than ordinary routine litigation incidental to the business of the Company
which is not otherwise material to the business or financial condition of the
Company.

BOARD COMPOSITION
 
  Following the Offering, the Board of Directors will consist of ten members,
which will include the nine current members of the Board plus one additional
"independent director" (within the meaning of the regulations of the New York
Stock Exchange (the "NYSE")) nominated for election by the Board of Directors.
It is expected that the new director will be elected by the Board within three
months following the closing of the Offering. Directors of the Company are
currently elected annually by its stockholders to serve during the ensuing
year or until their respective successors are duly elected and qualified.
Following the Offering, the Board of Directors will be divided into three
classes each of whose members will serve for a staggered three-year term. Upon
the expiration of the term of a class of directors, directors in such class
will be elected for three-year terms at the annual meeting of stockholders in
the year in which such term expires. See "Description of Capital Stock--
Certain Provisions of the Certificate of Incorporation and By-laws."
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  The Board of Directors currently has two committees: an Audit Committee and
a Compensation Committee.
 
  The Audit Committee will be comprised of the independent directors. The
Audit Committee reviews and recommends to the Board, as it deems necessary,
the internal accounting and financial controls for the Company and the
accounting principles and auditing practices and procedures to be employed in
preparation and review of financial statements of the Company. The Audit
Committee makes recommendations to the Board concerning the engagement of
independent public accountants and the scope of the audit to be undertaken by
such accountants. Price Waterhouse LLP presently serves as the independent
accountants of the Company.
 
  The Compensation Committee is currently comprised of Mr. Fisher, who,
following the Offering, will be joined by the two independent directors. The
Committee reviews and, as it deems appropriate, recommends to the Board
policies, practices and procedures relating to the compensation of the
officers and other managerial employees and the establishment and
administration of employee benefit plans. The Committee exercises all
authority under any employee stock option plans of the Company as the
Committee therein specifies (unless the Board resolution appoints any other
committee to exercise such authority), and advises and consults with the
officers of the Company as may be requested regarding managerial personnel
policies. The Committee will have such additional powers and be granted
additional authority as may be conferred upon it from time to time by the
Board.
 
COMPENSATION OF DIRECTORS
 
  Directors who are not executive officers or employees of the Company or
Softbank will receive an annual retainer of $25,000 for Board of Directors
service and a fee of $2,000 for each meeting of the Board of Directors or any
committee thereof attended.
   
  The Company has adopted the 1998 Non-Employee Directors Stock Option Plan
(the "Non-Employee Directors Plan"). Directors of the Company who are not
employees of the Company or any of its subsidiaries ("Non-Employee Directors")
will automatically participate in the Non-Employee Directors Plan.     
 
 
                                      60
<PAGE>
 
  Pursuant to the 1998 Non-Employee Directors Plan, each Non-Employee Director
shall receive upon election as a member of the Board an initial grant of stock
options to purchase 15,000 shares of Common Stock; provided, that each Non-
Employee Director who is on the Board of Directors on the date of the Offering
shall receive such initial grant of stock options on the date of the Offering.
Each Non-Employee Director shall automatically receive on each annual meeting
thereafter an annual grant of stock options to purchase 7,500 additional
shares of Common Stock. The terms of each stock option granted to a Non-
Employee Director shall provide that (i) the option price shall be equal to
100% of the fair market value (as defined in the 1998 Incentive Compensation
Plan) of the Common Stock on the date of grant, (ii) such option shall be
exercisable for a period of ten years following the date of grant, and (iii)
such option shall vest and become exercisable in five equal installments
beginning on the first anniversary of the date of grant.
 
  Upon ceasing to be a Non-Employee Director, such option shall terminate
except with respect to any portion of such option then exercisable, which
portion shall remain exercisable for a period of (x) 90 days, if the
termination as Director resulted from any reason other than death, disability
or Cause (as defined in the 1998 Incentive Compensation Plan), or (y) one
year, if the termination resulted from death or disability; provided, that in
the event the termination resulted from a removal for Cause, such option shall
immediately terminate and no longer be exercisable to any extent; provided,
further, that in no event shall any such option remain exercisable past the
remainder of its scheduled ten-year term.
 
  Upon a "change in control" of the Company (as defined in the Non-Employee
Directors Plan), each outstanding option shall fully vest and become
immediately exercisable in full. In addition, the Committee may provide in its
sole discretion that upon a change in control of the Company, each Non-
Employee Director shall be entitled to receive in cancellation of such Non-
Employee Director's outstanding and unexercised stock options, a cash payment
in an amount equal to the difference between the option price of such stock
options and (i) in the event the change of control is the result of a tender
offer or exchange offer for the Common Stock, the final offer price per share
paid for the Common Stock, multiplied by the number of shares of Common Stock
covered by such stock options, or (ii) in the event the change of control is
the result of any other occurrence, the aggregate value of the Common Stock
covered by such stock options, as determined by the Committee at such time.

STOCK PLANS
 
 Incentive Compensation Plan
 
  General.  The Company has adopted a 1998 Incentive Compensation Plan (the
"Plan") to provide long-term incentives for its key employees and enhance
shareholder value. The Plan will be administered by the Compensation Committee
(for purposes herein, the "Committee"), which will (i) select the
participants, determine the type of awards, and the number of shares or share
units subject to awards, and (ii) interpret the Plan and make all other
determinations necessary or advisable for its administration.
 
  All employees and consultants of the Company and its affiliates who have
demonstrated significant management potential or the capacity for contributing
substantially to the successful performance of the Company and its affiliates,
are eligible to be participants in the Plan. Awards may consist of stock
awards, stock options (either incentive stock options within the meaning of
Section 422 of the Internal Revenue Code or nonstatutory stock options), stock
appreciation rights, performance shares (which may be granted as performance
share units) and restricted stock (which may be granted as restricted stock
units).
 
  The Common Stock available for awards under the Plan shall not exceed
8,500,000 shares. In the event of any change in the outstanding shares by
reason of any stock dividend or split, recapitalization, merger or other
corporate change, or any distributions to common shareholders other than
regular cash dividends, the Committee may make such substitution or
adjustment, if any, as it deems to be equitable, as to the number or kind of
shares of Common Stock or other securities issued pursuant to the Plan and to
outstanding awards. Shares subject to an award that expires unexercised, is
forfeited, or terminated, or settled in cash in lieu of Common Stock, and
shares tendered to pay for the exercise of a stock option, shall thereafter
again be available for grant under the Plan.
 
  Each award under the Plan shall be evidenced by an agreement setting forth
the terms and conditions, as determined by the Committee, which apply to such
award. In the sole discretion of the Committee, a participant may be permitted
to defer the receipt of cash or Common Stock otherwise deliverable under any
award.
 
  Stock Options. The Committee shall establish the option price at the time
each stock option is granted, which price shall not be less than 100% of the
fair market value of the Common Stock on the date of grant. Stock options
shall vest and become exercisable at a rate determined by the Committee, and
shall remain exercisable for such period as specified by the Committee. The
award agreements in respect of options that are intended to qualify as
incentive stock options will contain any additional provisions necessary to
comply with the requirements of Section 422 of the Internal Revenue Code. In
no event may any employee receive in any calendar year grants of stock options
with respect to more than 1,000,000 shares of Common Stock.
 
  The option price of each share as to which a stock option is exercised will
be paid in full at the time of such exercise in cash, by tender of shares of
Common Stock owned by the participant valued at fair market value, by a "sale
to cover" broker transaction or other cashless exercise method permitted under
Regulation T of the Federal Reserve Board, or by a combination of cash, shares
of Common Stock and other consideration as the Committee deems appropriate.
 
  Stock Appreciation Rights. Stock appreciation rights ("SARs") may be granted
in tandem with a stock option or unrelated to a stock option. SARs shall vest
and become exercisable at a rate determined by the Committee, and shall remain
exercisable for such period as specified by the Committee. A SAR entitles its
holder to receive from the Company an amount equal to the excess of the fair
market value of a share of Common Stock on the exercise of the SAR over the
fair market value on the date of grant. The Committee may determine in its
sole discretion whether a SAR will be settled in cash, Common Stock or a
combination thereof. In no event may any employee receive in any calendar year
grants of SARs with respect to more than 500,000 shares of Common Stock.
 
  Performance Shares. Performance shares may be granted in the form of actual
shares of Common Stock or share units having a value equal to an identical
number of shares of Common Stock. The performance
 
                                      62
<PAGE>
 
conditions and the length of the performance period will be determined by the
Committee but in no event may a performance period be less than one year. The
Committee may determine in its sole discretion whether performance shares
granted in the form of share units shall be paid in cash, Common Stock, or a
combination thereof.
 
  Unless the Committee determines otherwise, awards of performance shares to a
Covered Employee will be subject to performance conditions based on the
achievement by the Company of target levels of items such as consolidated net
income, return on shareholders' equity, return on net assets or share price
performance. For purposes of the 1998 Incentive Compensation Plan, a "Covered
Employee" generally includes any employee that would be a covered employee
within the meaning of Section 162(m) of the Internal Revenue Code, and any
other employee of the Company or its subsidiaries designated by the Committee
in its discretion. The maximum number of performance shares subject to any
award to a Covered Employee is 500,000 for the first 12 months during the
performance period and each 12-month period thereafter.
 
  Restricted Stock. Restricted stock may be granted in the form of actual
shares of Common Stock or share units having a value equal to an identical
number of shares of Common Stock. The employment conditions and the length of
the period for vesting of restricted stock will be established by the
Committee at time of grant, except that each restriction period shall not be
less than twelve months. During the restricted period, shares of restricted
stock may not be sold, assigned, transferred or otherwise disposed of, or
pledged or hypothecated as collateral for a loan or as security for the
performance of any obligation or for any other purpose as the Committee shall
determine. The Committee may determine in its sole discretion whether
restricted stock granted in the form of share units will be paid in cash,
Common Stock or a combination thereof.
 
  Stock awards. In addition to awards of performance shares and restricted
stock, awards of Common Stock may be granted under the Plan in the form of
actual shares of Common Stock. Full ownership of such shares, whether issued
in the form of a certificate or in book entry, including the right to vote and
receive dividends, shall immediately vest in such participant.
 
  Change in Control. In the event of a Change in Control (as defined below):
(i) all stock options will be fully vested and exercisable in full (ii) all
SARs which have not been granted in tandem with stock options will become
exercisable in full (iii) the restrictions applicable to all shares of
restricted stock will lapse and such shares will be deemed fully vested and
all restricted stock granted in the form of share units will be paid in cash;
(iv) all performance shares will be deemed to be earned at target level; and
(v) all performance shares granted in the form of share units will be paid in
cash.
   
  For purposes of the Plan, "Change in Control" is generally defined as (i) a
change in the majority of the Board of Directors except upon consent of the
previous Board of Directors; (ii) certain mergers, consolidations or similar
corporate transactions in which the Company is not the surviving corporation
or entity; or (iii) the shareholders of the Company approve a plan of complete
liquidation or dissolution of the Company or a sale of all or substantially
all of the Company's assets; provided, that a Change in Control will not be
deemed to occur under clause (ii) if Softbank, directly or indirectly, is the
beneficial owner of more than 25% of the Company's voting securities or of the
voting securities of any surviving corporation, respectively.     
   
  Amendment and Termination. The Board of Directors may amend, suspend or
terminate the Plan or any portion thereof at any time, provided that (a) no
amendment will be made without stockholder approval (including an increase in
the number of shares reserved for issuance under the Plan) if such approval is
necessary to comply with any applicable law, regulations or stock exchange
rule, and (b) except as otherwise provided under the cashout provisions in the
event of a Change in Control, no amendment will be made that would adversely
affect the rights of a participant under any award previously granted, without
such participant's written consent.     
 
                                      63
<PAGE>
 
  Effective Date. The Plan will have a term of ten years from February 13,
1998, subject to earlier termination.
 
 Softbank Executive Stock Option Plans
 
  The SOFTBANK Group Executive Stock Option Plans (the "Softbank Plans")
authorize the grant of options to those officers, directors and key employees
of Softbank as selected by a committee appointed by the Board of Directors of
SOFTBANK Holdings Inc. The Softbank Plans authorize the granting of options to
purchase SOFTBANK Corp. common stock at not less than 100% of the closing
market price on the date the option is granted. As of December 31, 1997,
substantially all options granted become exercisable in various installments
over the first six anniversaries of the date of grant and expire ten years
after the date of grant.
 
  As of December 31, 1997, 966,986 options had been granted under the Softbank
Plans. On January 19, 1998, the exercise price of all options was reset at
4,000 Japanese yen per share, the market price of SOFTBANK Corp.'s common
stock on that date.
 
 Employee Stock Purchase Plan
 
  General. The Company has adopted an employee stock purchase plan (the "Stock
Purchase Plan"). The Stock Purchase Plan is intended to meet the applicable
requirements of Section 423 of the Internal Revenue Code and will be
administered by the Committee.
 
  Option to Purchase. Under the Stock Purchase Plan, all full-time and certain
part-time employees of the Company who meet certain minimum service
requirements will be eligible to purchase shares of Common Stock by means of
payroll deductions. Eligible employees may elect to participate in offering
periods by authorizing after-tax payroll deductions of between 1% and 10% (in
whole percentages) of their base pay for the purchase of shares of Common
Stock. The aggregate maximum number of shares of Common Stock purchasable
under the Stock Purchase Plan is 1,500,000, subject to adjustment by the
Committee in its sole discretion in the event of any increase, reduction or
change or exchange of shares of Common Stock for a different number or kind of
shares or other securities of the Company by reason of any stock dividend or
split, recapitalization, merger, consolidation, spin-off, combination or
exchange of shares or other corporate change, or any distribution to common
shareholders other than cash dividends. Upon the dissolution or liquidation of
the Company, or upon a reorganization, merger or consolidation of the Company
as a result of which the Company is not the surviving corporation, or upon a
sale of substantially all of the Company's assets, or a sale or distribution
of a subsidiary of the Company, any affected participant will thereafter be
entitled to receive, for each share of Common Stock subject to such
participant's option, the cash, securities and/or property which a holder of
one share of Common Stock was entitled to receive upon and at the time of such
transaction.
 
  The price at which shares of Common Stock will be purchased at the end of
each purchase period will be the lesser of (i) 85% of the Fair Market Value of
a share of Common Stock on the first business day of such purchase period or
(ii) 85% of the fair market value on the last business day of each purchase
period. No participating employee will be entitled in any calendar year to
purchase Common Stock having an aggregate fair market value as of the first

                             CERTAIN TRANSACTIONS
 
ARRANGEMENTS BETWEEN THE PRINCIPAL STOCKHOLDERS AND THE COMPANY
 
  The Company and Softbank have entered into certain agreements governing
ongoing business relationships between them, including: (i) a master license
agreement for Softbank's producing and distributing Ziff-Davis publications in
Japan; (ii) a license agreement for Softbank's operating ZDNet in Japan; and
(iii) a series of agreements, including a trademark license agreement,
technical assistance agreement and accounting and administrative services
agreement, pursuant to which the Company will manage all ZDCF trade shows and
conferences conducted in Japan, but owned by Softbank. Total revenue earned by
the Company from such trade show and conference agreements will approximate
50% of the pre-tax income generated by such trade shows and conferences.
 
  Softbank has given the Company an undertaking not to expand operations
involving (x) publishing information on computing and Internet-related
technology through the media of print, CD-Rom/DVD, Internet and television, or
(y) producing trade shows, conferences, exhibitions and similar events
primarily related to computing and Internet-related technology outside Japan
in competition with the Company without the prior approval of the Company's
management directors after consulting with the Company's independent
directors. This undertaking does not preclude investments by investment funds
managed by Softbank. Softbank manages certain venture capital funds which
invest in, among other things, computer and Internet-related companies. These
funds may be able to co-invest with the Company or compete with the Company
with respect to new investments. Softbank may develop new funds in the future,
which funds may compete with the Company for investment opportunities. The
Company has undertaken not to compete with Softbank in Japan without the prior
approval of SOFTBANK Corp.'s Board of Directors and to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest."
 
  The Company and Softbank entered into a Registration Rights Agreement, dated
as of April 1, 1998, in connection with the Offering. The Agreement entitles
Softbank to require the Company to register any or all of the Common Stock
held by it in a public offering pursuant to the Securities Act of 1933, as
amended, as well as to "piggyback" or include its shares of Common Stock in
any registration of Common Stock made by the Company.
 
CERTAIN RELATED PARTY TRANSACTIONS
 
  The Company is a member of a group of companies affiliated through common
ownership under SOFTBANK Corp. and has various transactions and relationships
with members of the group, including SOFTBANK Corp.'s wholly-owned U.S.
subsidiary, SOFTBANK Holdings Inc. ("SBH"). Because of these relationships, it
is possible that the terms of the various transactions are not those that
would result from an arm's length dealing among unrelated parties.
 
  In December 1994, as part of the acquisition of ZD Expos, MAC purchased a
portion of the trade show assets for $45 million and its parent company, Son
Kosan Ltd., purchased an additional portion for $30 million. Concurrently with
the purchase of assets, SB Forums and Son Kosan Inc. entered into a management
agreement pursuant to which SB Forums agreed to provide management services
with respect to certain Son Kosan operations in Japan, France and Germany. SB
Forums earned approximately $808,000, $1,667,000 and $2,644,000 for such
services for the years ended December 31, 1995, 1996 and 1997 respectively.
Son Kosan's trade show assets were sold to SB Forums for $10 million in
January 1997 and certain of MAC's trade show assets are being contributed to
ZDCF as part of the Reorganization. See "The Reorganization."
 
  In February 1996, as part of the acquisition of ZD Pubco, MAC purchased
certain publishing assets for $302 million in cash. Concurrently with the sale
of assets, ZDI and MAC entered into a management agreement pursuant to which
ZDI agreed to provide management services with respect to the purchased
assets. The
 
                                      66
<PAGE>
 
Company earned approximately $2 million for such services for each of the
years ended December 31, 1996 and 1997, respectively. Of these assets, a
portion was transferred to ZDI for $100 million as of October 31, 1997 and the
balance will be sold to ZDI for $270 million concurrently with the Offering.
See "The Reorganization." The purchase price for the assets sold to ZDI was
not more than fair market value as determined by an independent appraiser.
 
  ZDI and Softbank entered into a series of license and syndication agreements
pursuant to which Softbank was granted the license to publish, or use certain
materials from, PC Week, Computer Shopper, PC Computing, MacWeek, Computer
Gaming World, PC Magazine and Internet Business Advantage. The Company earned
approximately $963,948 and $1,817,986 in connection therewith for the years
ended December 31, 1996 and 1997, respectively. Such agreements are being
combined into the master license agreement described above.
 
  The Company has advanced funds for the account of MAC in managing the MAC
Assets and ZDTV, bearing interest at the 30-day LIBOR rate plus .50%; subject
to periodic reimbursement by MAC. Such advances totalled $8.1 million, $68.2
million and $70.9 million in 1995, 1996 and 1997, respectively. The remaining
outstanding amount as of December 31, 1997 of $42.6 million will be reimbursed
in connection with the Reorganization. See Note 9 to the Notes to the Combined
Financial Statements of ZDI and ZDCF.
 
  During 1996 and 1997, the Company recorded revenues of approximately $.9
million and $2.7 million, respectively, from sales of advertising space and
trade show services to Kingston, an 80%-owned Softbank partnership. These
services were provided under terms consistent with those provided to
unaffiliated customers. See Note 9 of the Notes to the Combined Financial
Statements. Concurrently with the Offering the Company is entering into a
sale-leaseback transaction with Kingston. See "The Reorganization."
 
  In 1997 the Company had an arrangement with SOFTBANK Interactive Marketing
("SIM"), a 65.3%-owned Softbank subsidiary, for providing interactive media
sales. The Company paid SIM approximately $.6 million and $1.8 million in
commissions for the years ended December 31, 1996 and 1997, respectively.
Effective December 31, 1997, SIM was acquired by an unrelated third party and
the Company terminated its representation agreement with SIM. See Note 9 of
the Notes to the Combined Financial Statements of ZDI and ZDCF.
 
  During 1996 and 1997, the Company and Softbank were parties to a joint
venture agreement pursuant to which the Company managed all ZDCF trade shows
and conferences conducted in Japan. The Company earned approximately
$1,727,000 and $1,413,000 for such services for the years ended December 31,
1996 and 1997, respectively.
 
  During 1996 and 1997, the Company incurred $2 million and approximately $1.6
million in advertising expenses with Yahoo! Inc., which is 29.4% owned by
Softbank. Mr. Yang is a co-founder and Chief Yahoo and Mr. Hippeau is a
director of Yahoo! Inc.
 
  During 1995 to 1997, the Company issued notes payable to Softbank in an
aggregate principal amount of $2.5 billion as of December 31, 1997,
principally for indebtedness incurred in the acquisition of ZD Expos, COMDEX
and ZD Pubco. See Note 9 of the Notes to the Combined Financial Statements.
 
  As part of the acquisition of the Company by its former owner in 1994, the
Company agreed to assume certain obligations to management arising out of
prior employment arrangements with Ziff Communications Company. In 1995 and
immediately after the end of the 1996 calendar year, the Company paid under
such arrangements $29,702,469 to Mr. Hippeau, the Company's Chairman and CEO
and a Director of the Company, and $1,014,565 to Mr. Sheer, the President of
ZD Publishing and a Director of the Company. See Note 9 to the Notes to the
Combined Financial Statements of ZDI and ZDCF.
 
  The Company has participated in the U.S. Softbank cash management program,
periodically transferring excess cash to SBH and in turn receiving cash
advances from SBH to fund the Company's short-term working capital
requirements. Under the program, interest is accrued based on the net balance
outstanding at the end of
 
                                      67
<PAGE>
 
each month. Interest income is earned at the 30-day LIBOR rate. Interest
expense is incurred at such rate plus .50%. As of December 31, 1996 and 1997,
such net cash transfers from the Company to SBH amounted to $41.3 million and
$76.5 million, respectively. See Note 9 of the Notes to the Combined Financial
Statements of ZDI and ZDCF.
 
  During 1997, the Company was a guarantor under SBH's $150 million loan
agreement with The Bank of New York, under which $102.5 million was
outstanding as of December 31, 1997, bearing interest at a weighted average
rate of 6.51% per annum. In March, 1998 this agreement was amended and
restated to increase the loan amount to $450 million. Under the amended
agreement, the Company is a guarantor under SBH's $450 million credit facility
with The Bank of New York, as agent, The Bank of New York and Morgan Stanley
Senior Funding, Inc., as lenders, and certain affiliate guarantors. The
agreement governing the credit facility contains certain restrictive covenants
and other provisions which bind the Company, but it does not prevent the
Company from consummating the Offering. Concurrently with the Reorganization,
the Company will repay obligations due to SBH; and it is expected that SBH
will use a portion of such proceeds to prepay the loans under the credit
facility and terminate the commitments thereunder.
 
  SBH and its subsidiary SBH Delaware have agreed to act as guarantors for
payments under the Company's lease for its new headquarters located at 28 East
28th Street, New York, New York. In addition, the various intercompany loans
from SBH Delaware to the Company were subordinated to the lease agreement. In
accordance with the terms of these agreements, these arrangements will
terminate when the Company and SBH meet minimum net worth levels of $850
million and $715 million, respectively, upon completion of the Offerings, at
which time the Company will become the sole guarantor under the lease.
 
  During 1997, the Company entered into an operating lease with GE Capital
Corp. for certain television production equipment that the Company subleased
to ZDTV on similar terms. This arrangement is expected to continue upon
completion of the Offering. The total amount of leased equipment will not
exceed $10 million.
 
  During 1997, the Company participated in a global insurance program
implemented by SBH. Upon completion of the Offering, it is expected that the
Company will remain a part of this program. The total amount of insurance
expenses allocated to the Company for the period from August 1, 1997 to July
30, 1998 does not exceed $1.35 million.

                         DESCRIPTION OF CAPITAL STOCK
 
  The following summary of certain provisions of the Company's capital stock
describes all material provisions of, but does not purport to be complete and
is subject to, and qualified in its entirety by, the Company's Certificate of
Incorporation and By-laws, copies of which have been filed as exhibits to the
Registration Statement of which this Prospectus forms a part and by the
provisions of applicable law. See "Additional Information."
 
  At the time of the Offering, the total amount of authorized capital stock of
the Company will be 130 million shares, consisting of 120 million shares of
Common Stock, par value $.01 per share, and 10 million shares of Preferred
Stock, par value $.01 per share (the "Preferred Stock"). Upon completion of
the Offering, 100 million shares of Common Stock and no shares of Preferred
Stock will be issued and outstanding. As of April 1, 1998, there were no
shares of Common Stock outstanding. The discussion herein describes the
Company's Amended and Restated Certificate of Incorporation (the "Certificate
of Incorporation") and By-laws, as anticipated to be in effect upon
consummation of the Offering, and their effect on the Common Stock.
 
  Prior to the Offering, there has been no public market for the Common Stock.
See "Risk Factors--No Prior Public Market; Possible Volatility of Stock
Price."
 
COMMON STOCK
   
  The shares of Common Stock to be issued in the Reorganization will be, and
the shares of Common Stock being offered by the Company will be upon payment
therefor, validly issued, fully paid and nonassessable. The holders of
outstanding shares of Common Stock are entitled to receive dividends out of
assets legally available therefor at such time and in such amounts as the
Board of Directors may from time to time determine. See "Dividend Policy." The
shares of Common Stock are not convertible and the holders thereof have no
preemptive or subscription rights to purchase any securities of the Company.
Upon liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive pro rata the assets of the Company which
are legally available for distribution, after payment of all debts and other
liabilities. Each outstanding share of Common Stock is entitled to one vote on
all matters submitted to a vote of the stockholders, including election of
directors. There is no cumulative voting. Except as otherwise required by law
or the Certificate of Incorporation, the Common Stock will vote on all matters
submitted to a vote of the stockholders, including election of directors.     
 
PREFERRED STOCK
   
  The Certificate of Incorporation provides that shares of Preferred Stock may
be issued in one or more series from time to time by the Board of Directors,
and the Board is expressly authorized to fix by resolution or resolutions the
designations and the powers, preferences and rights, and the qualifications,
limitations and restrictions thereof, of the shares of each series of
Preferred Stock, including without limitation the following: (a) the
distinctive serial designation of such series which shall distinguish it from
other series; (b) the number of shares included in such series; (c) the
dividend rate (or method of determining such rate) payable to the holders of
the shares of such series, any conditions upon which such dividends shall be
paid and the date or dates upon which such dividends shall be payable; (d)
whether dividends on the shares of such series shall be cumulative and, in the
case of shares of any series having cumulative dividend rights, the date or
dates or method of determining the date or dates from which dividends on the
shares of such series shall be cumulative; (e) the amount or amounts which
shall be payable out of the assets of the Company to the holders of the shares
of such series upon voluntary or involuntary liquidation, dissolution or
winding up the Company, and the relative rights of priority, if any, of
payment of the shares of such series; (f) the price or prices at which, the
period or periods within which and the terms and conditions upon which the
shares of such series may be redeemed, in whole or in part, at the option of
the Company or at the option of the holder or holders thereof or upon the
happening of a specified event or events; (g) the obligation, if any, of the
Company to purchase or redeem shares of such series pursuant to a sinking fund
or otherwise and the price or prices at which, the period or periods within
which and     
 
                                      70
<PAGE>
 
   
the terms and conditions upon which the shares of such series shall be
redeemed or purchased, in whole or in part, pursuant to such obligation; (h)
whether or not the shares of such series shall be convertible or exchangeable,
at any time or times at the option of the holder or holders thereof or at the
option of the Company or upon the happening of a specified event or events,
into shares of any other class or classes or any other series of the same or
any other class or classes of stock of the Company, and the price or prices or
rate or rates of exchange or conversion and any adjustments applicable
thereto; and (i) whether or not the holders of the shares of such series shall
have voting rights, in addition to the voting rights provided by law, and if
so the terms of such voting rights. Subject to the rights of the holders of
any series of Preferred Stock, the number of authorized shares of any class or
series of Preferred Stock may be increased or decreased (but not below the
number of shares thereof then outstanding) by the affirmative vote of the
holders of a majority of the outstanding shares entitled to vote, irrespective
of the provisions of Section 242(b)(2) of the General Corporation Law of
Delaware (the "DGCL") or any corresponding provision hereafter enacted.     
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BY-LAWS
 
 Staggered Board of Directors
 
  Following the Offering, the Board of Directors will consist of ten members.
The Certificate of Incorporation provides that the directors of the Company
will be divided into three classes, as nearly equal in number as reasonably
possible, as determined by the Board. The initial term of office of Class I
directors will expire at the first annual meeting of stockholders, the initial
term of office of Class II directors will expire at the second annual meeting
of stockholders and the initial term of office of Class III directors will
expire at the third annual meeting of stockholders, with each class of
directors to hold office until their successors have been duly elected and
qualified. At each annual meeting of stockholders, directors elected to
succeed the directors whose terms expire at such annual meeting shall be
elected to hold office for a term expiring at the annual meeting of
stockholders in the third year following the year of their election and until
their successors have been duly elected and qualified. The classification of
the Board will have the effect of making it more difficult for stockholders to
change the composition of the Board, because only a minority of the directors
are up for election at each annual meeting, and the Board may not be replaced
by vote of the stockholders at any one time.
 
 Number of Directors; Removal; Filling Vacancies
 
  The Certificate of Incorporation provides that the number of members of the
Board of Directors will be fixed from time to time pursuant to the By-laws.
The By-laws provide that the Board will consist of one or more members, the
number of which will be determined from time to time by the Board. The
Certificate of Incorporation and By-laws provide that in the event of any
increase or decrease in the authorized number of directors, (a) each director
then serving as such shall nevertheless continue as a director of the class of
which he is a member until the expiration of his current term, or his earlier
death, retirement, resignation, or removal, and (b) the newly created or
eliminated directorships resulting from such increase or decrease shall be
apportioned by the Board among the three classes of directors so as to
maintain such classes as nearly equal in number as reasonably possible. The
Certificate of Incorporation and By-laws provide that directors may be removed
only for cause except that a director who is also an officer may be removed
upon ceasing to be an officer. The By-laws provide that vacancies, whether
arising through death, retirement, resignation or removal of a director or
through an increase in the authorized number of directors of any class, may
only be filled by a majority vote of the remaining directors of the class in
which such vacancy occurs, or by the sole remaining director of that class if
one such director remains, or by the majority vote of the directors of the
remaining classes if no such director remains, or by stockholders at an annual
meeting of stockholders of the Company. A director elected to fill a vacancy
shall serve for the remainder of the then present term of office of the class
to which he is elected. These provisions would prevent any stockholder from
enlarging the Board and then filling the new directorships with such
stockholder's own nominees.
 
                                      71
<PAGE>
 
 No Stockholder Action by Written Consent; Special Meetings
 
  The Certificate of Incorporation and By-laws provide that any action
required or permitted to be taken by the stockholders of the Company must be
duly effected at a duly called annual or special meeting of such holders and
may not be taken by any consent in writing by such holders. The Certificate of
Incorporation and By-laws provide that special meetings of stockholders of the
Company may be called only by the Chairman of the Board or the Board pursuant
to a resolution stating the purpose or purposes thereof, and any power of
stockholders to call a special meeting is specifically denied. No business
other than that stated in the notice shall be transacted at any special
meeting. These provisions will have the effect of delaying consideration of a
stockholder proposal until the next annual meeting unless a special meeting is
called by the Chairman, Vice Chairman, President or the Board for
consideration of such proposal.
 
 Advance Notice for Stockholder Nominations and Proposals of New Business
 
  The By-laws require notice of any proposal to be presented by any
stockholder or of the name of any person to be nominated by any stockholder
for election as a director of the Company at a meeting of stockholders to be
delivered to the Secretary of the Company not less than 60 nor more than 90
days prior to the date of the meeting. Accordingly, failure by a stockholder
to act in compliance with the notice provisions will mean that the stockholder
will not be able to nominate directors or propose new business.
 
 Amendments
   
  The Certificate of Incorporation provides that the affirmative vote of the
holders of at least 80% of the stock entitled to vote generally in the
election of directors, voting together as a single class, or a majority of the
Board of Directors is required to amend provisions of the By-laws relating to
stockholder action without a meeting; the calling of special meetings; the
number (or manner of determining the number), election and term of the
Company's directors; the filling of vacancies; and the removal of directors.
    
CERTAIN PROVISIONS OF DELAWARE LAW
   
  Following the consummation of the Offering, the Company will be subject to
the "Business Combination" provisions of Section 203 of the DGCL. In general,
such provisions prohibit a publicly held Delaware corporation from engaging in
various "business combination" transactions with any "interested stockholder"
for a period of three years after the date of the transaction in which the
person became an "interested stockholder," unless: (i) the transaction is
approved by the Board of Directors prior to the date the "interested
stockholder" obtained such status; (ii) upon consummation of the transaction
which resulted in the stockholder becoming an "interested stockholder," the
"interested stockholder" owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding for
purposes of determining the number of shares outstanding those shares owned by
(a) persons who are directors and also officers and (b) employee stock plans
in which employee participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer; or (iii) on or subsequent to such date the "business
combination" is approved by the Board of Directors and authorized at an annual
or special meeting of stockholders by the affirmative vote of at least 66 2/3%
of the outstanding voting stock which is not owned by the "interested
stockholder." A "business combination" is defined to include mergers, asset
sales and other transactions resulting in financial benefit to a stockholder.
In general, an "interested stockholder" is a Person who, together with
affiliates and associates, owns (or within three years, did own) 15% or more
of a corporation's voting stock. The statute could prohibit or delay mergers
or other takeover or change in control attempts with respect to the Company
and, accordingly, may discourage attempts to acquire the Company.     
   
  Section 203 and the provision of the Company's Certificate of Incorporation
and By-laws described above may make it more difficult for a third party to
acquire, or discourage bids for, the Company. Section 203 and these provisions
could have the effect of inhibiting attempts to change the membership of the
Company's Board of Directors.

LIMITATIONS ON LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Section 102 of the DGCL authorizes a Delaware corporation to include a
provision in its certificate of incorporation limiting or eliminating the
personal liability of its directors to the corporation and its stockholders
for monetary damages for breach of the directors' fiduciary duty of care. The
duty of care requires that, when acting on behalf of the corporation,
directors exercise an informed business judgment based on all material
information reasonably available to them. Absent the limitations authorized by
such provision, directors are accountable to corporations and their
stockholders for monetary damages for conduct constituting gross negligence in
the exercise of their duty of care. Although Section 102 of the DGCL does not
change a director's duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or rescission. The Company's
Certificate of Incorporation and By-laws include provisions which limit or
eliminate the personal liability of its directors to the fullest extent
permitted by Section 102 of the DGCL. Consequently, a director or officer will
not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for (i) any breach
of the director's duty of loyalty to the Company or its stockholders, (ii)
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) unlawful payments of dividends or unlawful
stock repurchases, redemptions or other distributions and (iv) any transaction
from which the director derived an improper personal benefit.
 
  The Certificate of Incorporation and By-laws provide that the Company will
indemnify to the full extent permitted by law any person made or threatened to
be made a party to any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that such person or
such person's testator or intestate is or was a director, officer or employee
of the Company or serves or served at the request of the Company as a
director, officer or employee. The Certificate of Incorporation and By-laws
provide that expenses, including attorneys' fees, incurred by any such person
in defending any such action, suit or proceeding will be paid or reimbursed by
the Company promptly upon receipt by it of an undertaking of such person to
repay such expenses if it shall ultimately be determined that such person is
not entitled to be indemnified by the Company.
The inclusion of these indemnification provisions in the Company's Certificate
of Incorporation and By-laws is intended to enable the Company to attract
qualified persons to serve as directors and officers who might otherwise be
reluctant to do so.
 
  The directors and officers of the Company are insured under policies of
insurance maintained by the Company, subject to the limits of the policies,
against certain losses arising from any claim made against them by reason of
being or having been such officers or directors. In addition, the limited
liability provisions in the Certificate of Incorporation and the
indemnification provisions in the Certificate of Incorporation and By-laws may
discourage stockholders from bringing a lawsuit against directors for breach
of their fiduciary duty (including breaches resulting from grossly negligent
conduct) and may have the effect of reducing the likelihood of derivative
litigation against directors and officers, even though such an action, if
successful, might otherwise have benefitted the Company and it stockholders.
Furthermore, a stockholder's investment in the Company may be adversely
affected to the extent the Company pays the costs of settlement and damage
awards against directors and officers of the Company pursuant to the
indemnification provisions in the Company's By-laws. The limited liability
provisions in the Certificate of Incorporation will not limit the liability of
directors under federal securities laws.
 
LISTING
 
  The Common Stock has been approved for listing on the NYSE under the symbol
"ZD," subject to official notice of issuance.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is The Bank of New
York.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to the Offering, there has been no market for the Common Stock of the
Company. The Company can make no predictions as to the effect, if any, that
sales of shares or the availability of shares for sale will have on the market
price prevailing from the time. Nevertheless, sales of significant amounts of
Common Stock in the public market, or the perception that such sales may
occur, could adversely affect the prevailing market prices. See "Risk
Factors--Shares Eligible for Future Sale."
 
  Upon completion of the Offering, the Company expects to have 100,000,000
shares of Common Stock outstanding. Of the shares outstanding after the
Offering, the 25,800,000 shares of Common Stock (29,670,000 shares if the U.S.
Underwriters' over-allotment is exercised in full) sold in the Offering and
that portion of 100,000 shares which SOFTBANK Kingston, Inc. intends to sell
concurrently with the Offering pursuant to the Registration Statement of which
this Prospectus forms a part will be freely tradeable without restriction
under the Securities Act, except for any such shares which may be acquired by
an "affiliate" of the Company (an "Affiliate"), which shares will be subject
to the volume limitations of Rule 144. As defined in Rule 144, an Affiliate of
an issuer is a person that, directly or indirectly, through one or more
intermediaries, controls or is controlled by, or is under common control with,
such issuer.
 
  An aggregate of 74,100,000 shares of Common Stock held by existing
stockholders upon completion of the Offering will be "restricted securities"
(as that phrase is defined in Rule 144) and may not be resold in the absence
of registration under the Securities Act or pursuant to exemptions from such
registration, including among others, the exemption provided by Rule 144 under
the Securities Act. One year after the date of this Prospectus, such shares of
Common Stock will be eligible for sale in the public market pursuant to Rule
144, subject to the volume limitations and other restrictions described below.
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, if a period of at least one year has elapsed
since the later of the date the "restricted securities" were acquired from the
Company and the date they were acquired from an Affiliate, then the holder of
such restricted securities (including an Affiliate) is entitled to sell a
number of shares within any three-month period that does not exceed the
greater of 1% of the then outstanding shares of the Common Stock
(approximately 1,000,000 shares immediately after the Offering) or the average
weekly reported volume of trading of the Common Stock on the NYSE during the
four calendar weeks preceding such sale. The holder may only sell such shares
through unsolicited brokers' transactions. Sales under Rule 144 are also
subject to certain requirements pertaining to the manner of such sales,
notices of such sales and the availability of current public information
concerning the Company. Affiliates may sell shares not constituting restricted
shares in accordance with the foregoing volume limitations and other
requirements without regard to any holding period. Under Rule 144 (k), if a
period of at least two years has elapsed between the later of the date
restricted securities were acquired from the Company and the date they were
acquired from an Affiliate, as applicable, a holder of such restricted
securities who is not an Affiliate at the time of the sale and has not been an
Affiliate for at least three months prior to the sale would be entitled to
sell the shares immediately without regard to the volume limitations and other
restrictions described above.
 
  Any employee of the Company who purchased his or her shares of Common Stock
or received an option to purchase Common Stock pursuant to a written
compensation plan or contract while the Company was not subject to the
reporting requirements of the U.S. Securities Exchange Act of 1934, as amended
(the "Exchange Act") may be entitled to rely on the resale provisions of Rule
701 under the Securities Act, which permits nonaffiliates to sell their Rule
701 shares without having to comply with the current public information,
holding period, volume limitation or notice provisions of Rule 144 and permits
Affiliates to sell their Rule 701 shares without having to comply with the
holding period provision of Rule 144, in each case beginning 90 days after the
Company became subject to the reporting requirements of the Exchange Act.
 
  The Company and Softbank entered into a Registration Rights Agreement, dated
as of April 1, 1998 (the "Registration Rights Agreement"), in connection with
the Offering. The Registration Rights Agreement provides Softbank with the
right to require the Company to register any or all of the Common Stock held
by it in a public offering pursuant to the Securities Act of 1933, as amended.
Pursuant to the Registration Rights
 
                                      74
<PAGE>
 
Agreement, Softbank also has the right to "piggyback" or include its Common
Stock in any registration of Common Stock made by the Company.
   
  Notwithstanding the foregoing, in connection with the Offering, each of the
Company and SBH, which owns in aggregate 74.2 million shares of Common Stock,
has agreed that, without the prior written consent of Morgan Stanley & Co.
Incorporated on behalf of the Underwriters, during the period ending 180 days
after the date of the Prospectus, they will not, directly or indirectly, (i)
offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock (whether such shares or any such
securities are then owned by such person or are thereafter acquired directly
from the Company) or (ii) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of Common Stock, whether any such transaction described in clause
(i) or (ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise. The restrictions described in this paragraph
do not apply to (a) the sale to the Underwriters of the shares of Common Stock
under the Underwriting Agreement, (b) the issuance by the Company of shares of
Common Stock upon the exercise of an option or a warrant or the conversion of
a security outstanding on the date of this Prospectus of which the
Underwriters have been advised in writing, (c) transactions by any person
other than the Company relating to shares of Common Stock or other securities
acquired in open market transactions after the completion of the offering of
the shares, (d) the issuance of shares of Common Stock in connection with the
Reorganization, or (e) the sale of up to 65,000 shares of Common Stock issued
in exchange for the Kingston assets. In addition, SBH has agreed that, without
the prior written consent of Morgan Stanley & Co. Incorporated on behalf of
the Underwriters, neither it nor any of its affiliates will, during the period
ending 180 days after the date of the Prospectus, make any demand for, or
exercise any right with respect to, the registration of any shares of Common
Stock or any security convertible into or exercisable or exchangeable for
Common Stock.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
  The following summaries of certain material provisions of the Company's
Notes and Credit Facility do not purport to be complete and are subject to,
and qualified in their entirety by, the Company's Indenture (as defined below)
and Credit Facility, copies of which have been filed as exhibits to the
Registration Statement of which this Prospectus forms a part and by the
provisions of applicable law. See "Additional Information."
 
NOTES
 
 General
 
  The Notes are to be issued under an Indenture, to be dated as of      , 1998
(the "Indenture"), between the Company and The Bank of New York, as trustee
(the "Trustee"). The Notes are general unsecured senior subordinated
obligations of the Company, and will rank on a parity with all other unsecured
and subordinated indebtedness of the Company. The Notes will be subordinated
in right of payment to all senior indebtedness of the Company (including
indebtedness under the Credit Agreement) as well as all other Senior
Indebtedness (as defined in the Indenture).
 
  The Notes will be limited to $250,000,000 aggregate principal amount and
will mature on      , 2008. Interest on the Notes will be payable on      and
      of each year, commencing      , 1998 at the rate of  % per annum. The
Notes will be redeemable, at the Company's option, in whole or in part, at any
time after      , 2003, at redemption prices starting at   % of their
principal amount and declining to 100% of their principal amount on or after
     , 2006 plus accrued and unpaid interest. In addition, upon a change of
control of the Company, each holder of Notes will have the right to require
the Company to purchase such holder's Notes. The Company will be permitted to
redeem a portion of the Notes following one or more public equity offerings
consummated prior to      , 2001.
 
 Covenants
 
  The Indenture contains certain restrictive covenants, including, among
others, the following: (i) a limitation on the ability of the Company and its
Restricted Subsidiaries (as defined in the Indenture) to incur any
indebtedness other than Permitted Indebtedness (as defined in the Indenture)
or to incur senior subordinated indebtedness or certain indebtedness secured
by liens; (ii) a limitation on the ability of the Company and its Restricted
Subsidiaries to, directly or indirectly, make any Restricted Payment (as
defined in the Indenture), including payment of dividends, prepayment of
subordinated indebtedness and the repurchase of capital stock; (iii) a
limitation on the ability of the Company to suffer to exist certain dividend
and other payment restrictions affecting its Restricted Subsidiaries; (iv) a
limitation on the ability of the Company to sell or to permit any Restricted
Subsidiary to issue or sell capital stock of a Restricted Subsidiary; (v) a
limitation on the ability of the Company and its Restricted Subsidiaries to
consummate certain Asset Sales (as defined in the Indenture) unless certain
conditions are fulfilled; and (vi) limitations on any transaction with
affiliates. Certain of these covenants will terminate if and when the Notes
receive an investment grade rating.
 
  In addition, the Indenture limits the ability of the Company to merge with
or to transfer all or substantially all of its assets to another person.
Except as set forth above, the Indenture does not contain any material
quantitative financial requirements. The Notes provide for acceleration upon
customary events of default.
 
CREDIT FACILITY
   
  The Company has obtained a commitment letter from The Bank of New York,
Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase Manhattan
Bank to provide a $1.35 billion term Credit Facility. In connection with the
Reorganization, the Company will enter into the Credit Facility and borrow
$1.25 billion thereunder. The Credit Facility will consist of a seven year
$500 million reducing revolving credit facility (with $400 million drawn at
consummation of the Offerings), a seven year $450 million term loan and an
eight year     
 
                                      76
<PAGE>
 
   
$400 million term loan. The revolving credit commitments will be reduced and
the $450 million term loan will be amortized, beginning in September 2000, by
(x) 10% in 2000, in two equal quarterly installments, (y) 20% in each of 2001,
2002, 2003 and 2004 in four equal quarterly installments and (z) 10% at final
maturity in March 2005. The $400 million term loan will be amortized,
beginning in September 2000, by (x) $2 million in 2000, in two equal quarterly
installments, (y) $4 million in each of 2001, 2002, 2003, 2004 and 2005 in
four equal quarterly installments and (z) $378 million at final maturity in
March 2006. The Credit Facility will be secured, in part, by a first priority
security interest in capital stock of certain subsidiaries of the Company and
will be guaranteed by certain wholly-owned domestic subsidiaries of the
Company (in each case, including ZDI and ZDCF).     
 
  The Credit Facility will contain certain customary affirmative and negative
covenants, including covenants (subject to certain exceptions) with respect
to, among other things, the delivery of financial statements and other
information, limitations on dispositions of assets, changes of business and
ownership, mergers or acquisitions, restricted payments, indebtedness, loans
and investments, and transactions with affiliates, negative pledge of assets,
maintenance of adequate and customary insurance coverage, compliance with all
applicable laws and regulations, and restriction on modifications of certain
agreements, charter documents or other material documents without the consent
of the lenders. The Credit Facility will also contain certain financial
covenants.
 
  The failure to satisfy any of the covenants would constitute an Event of
Default under the Credit Facility. The Credit Facility will also include other
customary events of default, including, without limitation, nonpayment,
misrepresentation in a material respect, cross-default to other indebtedness,
bankruptcy, ERISA, judgments and change of control.
 
  The Credit Facility is subject to certain terms and conditions, including
without limitation negotiation, execution and delivery of definitive financing
agreements, in each case containing terms and conditions, representations and
warranties, covenants, indemnifications, events of default and conditions to
lending. There can be no assurance as to when or whether the Credit Facility
will be entered into or as to whether the Credit Facility will contain the
terms and conditions described above, and such may contain terms and
conditions more favorable or less favorable to the Company than set forth
above.

                    CERTAIN UNITED STATES TAX CONSEQUENCES
                      TO NON-U.S. HOLDERS OF COMMON STOCK
 
  The following is a general discussion of the material United States federal
income and estate tax consequences of the ownership and disposition of Common
Stock by a person that, for United States federal income tax purposes, is a
non-resident alien individual, a foreign corporation, a foreign partnership or
an estate or trust, in each case not subject to United States federal income
tax on a net income basis in respect of income or gain from Common Stock (a
"non-U.S. holder"). This discussion does not consider the specific facts and
circumstances that may be relevant to particular holders in light of their
personal circumstances and does not address the treatment of non-U.S. holders
of Common Stock under the laws of any state, local or foreign taxing
jurisdiction. Further, the discussion is based on provisions of the United
States Internal Revenue Code of 1986, as amended (the "Code"), Treasury
regulations thereunder, and administrative and judicial interpretations
thereof, all as in effect on the date hereof and all of which are subject to
change on a possibly retroactive basis. Each prospective holder is urged to
consult a tax advisor with respect to the United States federal tax
consequences of acquiring, holding and disposing of Common Stock, as well as
any tax consequences that may arise under the laws of any state, local or
foreign taxing jurisdiction.
 
DIVIDENDS
 
  Dividends paid to a non-U.S. holder of Common Stock will be subject to
withholding of United States federal income tax at a 30% rate or such lower
rate as may be specified by an applicable income tax treaty, unless the
dividends are effectively connected with the conduct of a trade or business
within the United States (and are attributable to a United States permanent
establishment of such holder, if an applicable income tax treaty so requires
as a condition for the non-U.S. holder to be subject to United States income
tax on a net income basis in respect of such dividends). Such "effectively
connected" dividends are subject to tax at rates applicable to United States
citizens, resident aliens and domestic United States corporations, and are not
generally subject to withholding. Any such effectively connected dividends
received by a non-United States corporation may also, under certain
circumstances, be subject to an additional "branch profits tax" at a 30% rate
or such lower rate as may be specified by an applicable income tax treaty.
 
  Under currently effective United States Treasury regulations, dividends paid
to an address in a foreign country are presumed to be paid to a resident of
that country (unless the payor has knowledge to the contrary) for purposes of
the withholding discussed above and, under the current interpretation of
United States Treasury regulations, for purposes of determining the
applicability of a tax treaty rate. Under recently finalized United States
Treasury regulations that will generally be effective for distributions after
December 31, 1999 (the "Final Withholding Regulations"), however, a non-U.S.
holder of Common Stock who wishes to claim the benefit of an applicable treaty
rate would be required to satisfy applicable certification requirements. In
addition, under the Final Withholding Regulations, in the case of Common Stock
held by a foreign partnership, (x) the certification requirement would
generally be applied to the partners of the partnership and (y) the
partnership would be required to provide certain information, including a
United States taxpayer identification number. The Final Withholding
Regulations also provide look-through rules for tiered partnerships.
 
  A non-U.S. holder of Common Stock that is eligible for a reduced rate of
United States withholding tax pursuant to a tax treaty may obtain a refund of
any excess amounts currently withheld by filing an appropriate claim for
refund with the United States Internal Revenue Service.
 
GAIN ON DISPOSITION OF COMMON STOCK
 
  A non-U.S. holder generally will not be subject to United States federal
income tax in respect of gain recognized on a disposition of Common Stock
except in the following circumstances: (i) the gain is effectively connected
with a trade or business conducted by the non-U.S. holder in the United States
(and is attributable to a permanent establishment maintained in the United
States by such non-U.S. holder if an applicable income tax treaty so requires
as a condition for such non-U.S. holder to be subject to United States
taxation on a net income
 
                                      78
<PAGE>
 
basis in respect of gain from the sale or other disposition of the Common
Stock); (ii) in the case of a non-U.S. holder who is an individual and holds
the Common Stock as a capital asset, such holder is present in the United
States for 183 or more days in the taxable year of the sale and certain other
conditions exist; (iii) the Company is or has been a "United States real
property holding corporation" for federal income tax purposes and, in the
event that the Common Stock is considered "regularly traded on an established
securities market," the non-U.S. holder held, directly or indirectly at any
time during the five-year period ending on the date of disposition, more than
5% of the Common Stock (and is not eligible for any treaty exemption); or (iv)
the non-U.S. holder is subject to tax pursuant to certain provisions of the
Code applicable to U.S. expatriates. Effectively connected gains realized by a
corporate non-U.S. Holder may also, under certain circumstances, be subject to
an additional "branch profits tax" at a 30% rate or such lower rate as may be
specified by an applicable income tax treaty.
 
  The Company believes it is not currently, and does not anticipate becoming,
a "United States real property holding corporation" for federal income tax
purposes.
 
FEDERAL ESTATE TAXES
 
  Common Stock held by a non-U.S. holder at the time of death will be included
in such holder's gross estate for United States federal estate tax purposes,
unless an applicable estate tax treaty provides otherwise.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  Under current law, United States information reporting requirements (other
than reporting of dividend payments for purposes of the withholding tax noted
above) and backup withholding tax generally will not apply to dividends paid
to non-U.S. holders that are either subject to the 30% withholding discussed
above or that are not so subject because an applicable tax treaty reduces such
withholding. Otherwise, backup withholding of United States federal income tax
at a rate of 31% may apply to dividends paid with respect to Common Stock to
holders that are not "exempt recipients" and that fail to provide certain
information (including the holder's United States taxpayer identification
number). Generally, unless the payor of dividends has definite knowledge that
the payee is a United States person, the payor may treat dividend payments to
a payee with a foreign address as exempt from information reporting and backup
withholding. However, under the Final Withholding Regulations, dividend
payments generally will be subject to information reporting and backup
withholding unless applicable certification requirements are satisfied. See
the discussion above with respect to the rules applicable to foreign
partnerships under the Final Withholding Regulations.
 
  In general, United States information reporting and backup withholding
requirements also will not apply to a payment made outside the United States
of the proceeds of a sale of Common Stock through an office outside the United
States of a non-United States broker. However, United States information
reporting (but not backup withholding) requirements will apply to a payment
made outside the United States of the proceeds of a sale of Common Stock
through an office outside the United States of a broker (i) that is a United
States person, (ii) that derives 50% or more of its gross income for certain
periods from the conduct of a trade or business in the United States, (iii)
that is a "controlled foreign corporation" as to the United States, or (iv)
(effective beginning January 1, 2000) a foreign partnership, if at any time
during its tax year, one or more of its partners are U.S. persons (as defined
in U.S. Treasury regulations) who in the aggregate hold more than 50% of the
income or capital interest in the partnership or if, at any time during its
tax year, such foreign partnership is engaged in a United States trade or
business, unless the broker has documentary evidence in its records that the
holder or beneficial owner is a non-United States person or the holder or
beneficial owner otherwise establishes an exemption. Payment of the proceeds
of the sale of Common Stock to or through a United States office of a broker
is currently subject to both United States backup withholding and information
reporting unless the holder certifies its non-United States status under
penalties of perjury or otherwise establishes an exemption.
 
  A non-United States holder generally may obtain a refund of any excess
amounts withheld under the backup withholding rules by filing the appropriate
claim for refund with the United States Internal Revenue Service.

  The U.S. Underwriters and the International Underwriters, and the U.S.
Representatives and the International Representatives, are collectively
referred to as the "Underwriters" and the "Representatives," respectively. The
Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to
take and pay for all of the shares of Common Stock offered hereby (other than
those covered by the U.S. Underwriters' over-allotment option described below)
if any such shares are taken.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented and agreed that, with certain exceptions: (i)
it is not purchasing any Shares (as defined herein) for the account of anyone
other than a United States or Canadian Person (as defined herein) and (ii) it
has not offered or sold, and will not offer or sell, directly or indirectly,
any Shares or distribute any prospectus relating to the Shares outside the
United States or Canada or to anyone other than a United States or Canadian
Person. Pursuant to the Agreement between U.S. and International Underwriters,
each International Underwriter has represented and agreed that, with certain
exceptions: (i) it is not purchasing any Shares for the account of any United
States or Canadian Person and (ii) it has not offered or sold, and will not

or Canadian Person. With respect to any Underwriter that is a U.S. Underwriter
and an International Underwriter, the foregoing representations and agreements
(i) made by it in its capacity as a U.S. Underwriter apply only to it in its
capacity as a U.S. Underwriter and (ii) made by it in its capacity as an
 
                                      80

International Underwriter apply only to it in its capacity as an International
Underwriter. The foregoing limitations do not apply to stabilization
transactions or to certain other transactions specified in the Agreement
between U.S. and International Underwriters. As used herein, "United States or
Canadian Person" means any national or resident of the United States or
Canada, or any corporation, pension, profit-sharing or other trust or other
entity organized under the laws of the United States or Canada or of any
political subdivision thereof (other than a branch located outside the United
States and Canada of any United States or Canadian Person), and includes any
United States or Canadian branch of a person who is otherwise not a United
States or Canadian Person. All shares of Common Stock to be purchased by the
Underwriters under the Underwriting Agreement are referred to herein as the
"Shares."
 
  Pursuant to the Agreement between U.S. and International Underwriters, sales
may be made between the U.S. Underwriters and International Underwriters of
any number of Shares as may be mutually agreed. The per share price of any
Shares sold shall be the public offering price set forth on the cover page
hereof, in United States dollars, less an amount not greater than the per
share amount of the concession to dealers set forth below.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented that it has not offered or sold, and has
agreed not to offer or sell, any Shares, directly or indirectly, in any
province or territory of Canada or to, or for the benefit of, any resident of
any province or territory of Canada in contravention of the securities laws
thereof and has represented that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which such offer or sale is made.
Each U.S. Underwriter has further agreed to send to any dealer who purchases
from it any of the Shares a notice stating in substance that, by purchasing
such Shares, such dealer represents and agrees that it has not offered or
sold, and will not offer or sell, directly or indirectly, any of such Shares
in any province or territory of Canada or to, or for the benefit of, any
resident of any province or territory of Canada in contravention of the
securities laws thereof and that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which such offer or sale is made,
and that such dealer will deliver to any other dealer to whom it sells any of
such Shares a notice containing substantially the same statement as contained
in this sentence.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has represented and agreed that (i) it has not
offered or sold and, prior to the date six months after the closing date for
the sale of the Shares to the International Underwriters, will not offer or
sell, any Shares to persons in the United Kingdom except to persons whose
ordinary activities involve them in acquiring, holding, managing or disposing
of investments (as principal or agent) for the purposes of their businesses or
otherwise in circumstances which have not resulted and will not result in an
offer to the public in the United Kingdom within the meaning of the Public
Offers of Securities Regulations 1995; (ii) it has complied and will comply
with all applicable provisions of the Financial Services Act 1986 with respect
to anything done by it in relation to the Shares in, from or otherwise
involving the United Kingdom; and (iii) it has only issued or passed on and
will only issue or pass on in the United Kingdom any document received by it
in connection with the offering of the Shares to a person who is of a kind
described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 or is a person to whom such document
may otherwise lawfully be issued or passed on.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has further represented that it has not offered or
sold, and has agreed not to offer or sell, directly or indirectly, in Japan or
to or for the account of any resident thereof, any of the Shares acquired in
connection with the distribution contemplated hereby, except for offers or
sales to Japanese International Underwriters or dealers and except pursuant to
any exemption from the registration requirements of the Securities and
Exchange Law and otherwise in compliance with applicable provisions of
Japanese law. Each International Underwriter has further agreed to send to any
dealer who purchases from it any of the Shares a notice stating in substance
that, by purchasing such Shares, such dealer represents and agrees that it has
not offered or sold, and will not offer or sell, any of such Shares, directly
or indirectly, in Japan or to or for the account of any resident thereof
except for offers or sales to Japanese International Underwriters or dealers
and except pursuant to any exemption from the registration requirements of the
Securities and Exchange Law and otherwise in compliance with applicable
 
                                      81
<PAGE>
 
provisions of Japanese law, and that such dealer will send to any other dealer
to whom it sells any of such Shares a notice containing substantially the same
statement as contained in this sentence.
 
  The Underwriters initially propose to offer part of the shares of Common
Stock directly to the public at the public offering price set forth on the
cover page hereof and part to certain dealers at a price that represents a
concession not in excess of $          a share under the public offering
price. Any Underwriter may allow, and such dealers may reallow, a concession
not in excess of $               a share to other Underwriters or to certain
other dealers. After the initial offering of the shares of Common Stock, the
offering price and other selling terms may from time to time be varied by the
Representatives.
 
  The Company has granted to the U.S. Underwriters an option, exercisable for
30 days from the date of this Prospectus, to purchase up to an aggregate of
3,870,000 additional shares of Common Stock at the public offering price set
forth on the cover page hereof, less underwriting discounts and commissions.
The U.S. Underwriters may exercise such option solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
shares of Common Stock offered hereby. To the extent such option is exercised,
each U.S. Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of Common
Stock as the number set forth next to such U.S. Underwriter's name in the
preceding table bears to the total number of shares of Common Stock set forth
next to the names of all U.S. Underwriters in the preceding table.
 
  The Common Stock has been approved for listing on the New York Stock
Exchange under the symbol "ZD," subject to official notice of issuance. In
order to meet the requirements for listing the Common Stock on the New York
Stock Exchange, the Underwriters have undertaken to meet the New York Stock
Exchange's minimum distribution, issuance and aggregate market value
requirements.
 
  At the request of the Company, the Underwriters have reserved shares of
Common Stock offered hereby for sale, at the initial public offering price, up
to 1,550,000 shares to be issued by the Company and offered hereby for
directors, officers, employees, business associates and related persons of the
Company. The number of shares of Common Stock available for sale to the
general public will be reduced to the extent such individuals purchase such
reserved shares. Any reserved shares which are not so purchased will be
offered by the Underwriters to the general public on the same basis as the
other shares offered hereby.
   
  Each of the Company and SBH has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the Underwriters,
during the period ending 180 days after the date of the Prospectus, they will
not, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase, lend, or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock
(whether such shares or any such securities are then owned by such person or
are thereafter acquired directly from the Company) or (ii) enter into any swap
or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of Common Stock, whether any such
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise. The
restrictions described in this paragraph do not apply to (a) the sale to the
Underwriters of the shares of Common Stock under the Underwriting Agreement,
(b) the issuance by the Company of shares of Common Stock upon the exercise of
an option or a warrant or the conversion of a security outstanding on the date
of this Prospectus of which the Underwriters have been advised in writing, (c)
transactions by any person other than the Company relating to shares of Common
Stock or other securities acquired in open market transactions after the
completion of the offering of the Shares, (d) the issuance of shares of Common
Stock in connection with the Reorganization or (e) the sale of up to 65,000
shares of Common Stock issued in exchange for the Kingston assets. In
addition, SBH has agreed that, without the prior written consent of Morgan
Stanley & Co. Incorporated on behalf of the Underwriters, neither it nor any
of its affiliates will, during the period ending 180 days after the date of
the Prospectus, make any demand for, or exercise any right with respect to,
the registration of any shares of Common Stock or any security convertible
into or exercisable or exchangeable for Common Stock.     
 
                                      82
<PAGE>
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
 
  In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may over-allot in
connection with the Offering, creating a short position in the Common Stock
for their own account. In addition, to cover over-allotments or to stabilize
the price of the Common Stock, the Underwriters may bid for, and purchase,
shares of Common Stock in the open market. Finally, the underwriting syndicate
may reclaim selling concessions allowed to an Underwriter or a dealer for
distributing the Common Stock in the Offering if the syndicate repurchases
previously distributed shares of Common Stock in transactions to cover
syndicate short positions, in stabilization transactions or otherwise. Any of
these activities may stabilize or maintain the market price of the Common
Stock above independent market levels. The Underwriters are not required to
engage in these activities, and may end any of these activities at any time.
 
  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
 
  The Underwriters have agreed to reimburse the Company for a portion of the
Company's expenses in connection with the Offering.
 
  Concurrently with the Offering, SOFTBANK Kingston Inc., an affiliate of the
Company and a wholly-owned subsidiary of SBH, intends to sell a portion of the
100,000 shares of Common Stock of the Company issued to Kingston in exchange
for certain assets transferred to the Company which shares are included in the
Registration Statement of which this Prospectus forms a part. SOFTBANK
Kingston Inc. may sell such shares directly to purchasers or to or through
underwriters, brokers/dealers or agents. See "The Reorganization" and
"Principal Stockholders."
 
  Certain of the Underwriters from time to time perform various investment
banking services for the Company and Softbank, for which such Underwriters
receive compensation. Morgan Stanley, Merrill Lynch and DLJ are also acting as
underwriters in connection with the Notes Offering and will receive customary
discounts and commissions in connection therewith. Morgan Stanley Senior
Funding, an affiliate of Morgan Stanley, and DLJ Capital Funding, an affiliate
of DLJ, will each act as an agent and a lender under the Credit Facility and
will receive fees pursuant to the Credit Facility customary to performing such
services. In addition, Morgan Stanley Senior Funding is currently a lender to
SBH under a $450 million revolving credit facility and will receive fees
pursuant to such financing arrangement customary to performing such services.
 
PRICING OF OFFERING
 
  Prior to the Offering, there has been no public market for the Common Stock.
Consequently, the initial public offering price for the Common Stock will be
determined by negotiations between the Company and the Representatives. Among
the factors to be considered in determining the initial public offering price
will be the Company's record of operations, the Company's current financial
position and future prospects, the experience of its management, the economics
of the industry in general, the general condition of the equity securities
markets, sales, earnings and certain other financial operation information of
the Company in recent periods, the price-earnings ratios, price-sales ratios,
market prices of securities and certain financial and operating information of
companies engaged in activities similar to those of the Company. The estimated
initial public offering price range set forth on the cover page of this
Preliminary Prospectus is subject to change as a result of market conditions
and other factors.
 
                                 LEGAL MATTERS
 
  The validity of the Common Stock offered hereby will be passed upon for the
Company by Sullivan & Cromwell, New York, New York, U.S. counsel to the
Company. Stephen A. Grant, a partner of Sullivan & Cromwell, owns 5,350 shares
of common stock of SOFTBANK Corp., which are held in a retirement account.
Certain legal matters will be passed upon for the Underwriters by Davis Polk &
Wardwell, New York, New York.

To the Board of Directors of
ZD Inc.
 
In our opinion, the accompanying balance sheet presents fairly, in all
material respects, the financial position of ZD Inc. at March 27, 1998 in
conformity with generally accepted accounting principles. This balance sheet
is the responsibility of the Company's management; our responsibility is to
express an opinion on this balance sheet based on our audit. We conducted our
audit in accordance with generally accepted auditing standards which require
that we plan and perform the audit to obtain reasonable assurance about
whether the balance sheet is free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the balance sheet, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall balance sheet
presentation. We believe that our audit provides a reasonable basis for the
opinion expressed above.

                            NOTES TO BALANCE SHEET
 
1. ORGANIZATION
 
  ZD Inc. (the "Company") is a newly formed nonstock corporation incorporated
in the State of Delaware on February 4, 1998. Upon completion of the
reorganization discussed below, the Company will be a majority-owned indirect
subsidiary of SOFTBANK Corp. and affiliates ("Softbank"). The Company's
capital structure after the reorganization will consist of 10,000,000
authorized shares of $.01 par value preferred stock with no shares issued and
outstanding and 120,000,000 authorized shares of $.01 shares of common stock
with 74,200,000 shares issued and outstanding.
 
  The Company was formed to effect the reorganization of ZDI (Ziff-Davis Inc.)
and ZDCF (ZD COMDEX and Forums Inc.), both indirect wholly-owned subsidiaries
of Softbank. The reorganization is expected to be completed in the second
quarter of 1998 and will be accounted for in a manner similar to a pooling of
interests as the Company, ZDI and ZDCF will be companies under common control.
 
  There have been no operations of ZD Inc. as of March 27, 1998, and,
accordingly, statements of ZD Inc.'s operations and cash flows have not been
included herein.
 
2. FINANCING ARRANGEMENTS
 
  The Company expects to raise approximately $400,000,000 from the initial
public offering of its Common Stock, approximately $250,000,000 in notes, and
approximately $1,250,000,000 of senior bank debt. There can be no assurances
that the expected levels of financing from the Common Stock and Notes
Offerings will be obtained.
   
  The Company has obtained a commitment from a group of banks to enter into a
$1.35 billion Credit Facility. The Credit Facility will consist of a seven-
year $500 million reducing revolving credit facility (with $400 million drawn
at closing), a seven-year $450 million term loan and an eight-year $400
million term loan. The revolving credit will be available for loans, letters
of credit, and swing-line loans, subject to a certain maximum level of
borrowing. The revolving credit commitments will be reduced and the $450 term
loan will be amortized, beginning in September 2000, by (x) 10% in 2000, in
two equal quarterly installments, (y) 20% in each of 2001, 2002, 2003 and 2004
in four equal quarterly installments and (z) 10% at final maturity in March
2005. The $400 million term loan will be amortized, beginning in September
2000, by (x) $2 million in 2000 in two equal quarterly installments, (y) $4
million in each of 2001, 2002, 2003, 2004 and 2005 in four equal quarterly
installments and (z) $378 million at final maturity n March 2006. The Credit
Agreement will also provide the Company the ability to increase the revolving
credit portion by $300 million to $800 million at any time prior to June, 2000
if the banks agree to increase their commitments.     
 
  Loans under both the revolving credit and term loan portions of the Credit
Facility will bear interest at either LIBOR plus an applicable margin or the
Alternate Base Rate plus an applicable margin. The applicable margin will be
based on a pricing grid to be determined by the Company's ratio of total debt
to EBITDA. The Company will also pay a commitment fee on the unused portion of
the revolving credit.
 
  The funds raised will be used to retire substantially all of the existing
notes payable to Softbank and its affiliates of ZDI and ZDCF, and for the
purchase of certain assets from affiliated companies.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
1. THE COMPANIES AND BASIS OF PRESENTATION
 
  The combined financial statements include the accounts of ZDI (Ziff-Davis
Inc.) and ZDCF (ZD COMDEX and Forums, Inc.) and their subsidiaries and
predecessor companies (collectively the "Companies"). The Companies are
wholly-owned indirect subsidiaries of SOFTBANK Corp. ("Softbank"), a Japanese
corporation which, as of December 31, 1997, was 50.2% owned by Mr. Son, its
President, including 43.4% directly owned by his wholly-owned holding company,
MAC Inc. ( "MAC"), also a Japanese corporation.
 
  As further described below, the combined financial statements include the
accounts of COMDEX (formerly Softbank COMDEX, Inc.) and ZDI as of their
respective acquisition dates and Forums (formerly Softbank Forums Inc.) for
all periods presented. Effective December 31, 1997, COMDEX and Forums merged
and the surviving company was renamed ZD COMDEX and Forums Inc.
 
  The Companies operate in two business segments: (i) publishing and (ii)
trade shows and conferences.
 
 Publishing
 
  The publishing segment is engaged in publishing magazines, journals,
newsletters, electronic information products, training manuals and providing
market research about the computer industry. The publishing segment's
principal operations are in the United States and Europe, although it also
licenses or syndicates its editorial content to over 50 other publications
distributed worldwide.
 
 Trade shows and conferences
 
  The trade shows and conferences segment is engaged in the organization,
production and management of trade shows, conferences and seminars for the
computer industry. The trade shows and conferences segment's principal
operations are in the United States and to a lesser extent in Europe and Asia.
 
 Acquisition of ZDI (formerly Ziff-Davis Publishing Company and Ziff-Davis
Holdings Corp.)
 
  In February 1996, Softbank acquired the stock of Ziff-Davis Holdings Corp.
("Holdings") for an aggregate purchase price of approximately $1,800,000, plus
transaction costs. Concurrent with the acquisition, in a separate agreement,
MAC Inc., directly or through wholly-owned affiliates, acquired certain of the
assets and assumed certain of the liabilities of ZDI (the "MAC Assets") for an
aggregate purchase price of approximately $302,000.
 
  The acquisitions of ZDI by the Companies and the MAC Assets by MAC Inc. have
been accounted for as of February 29, 1996 using the purchase method of
accounting. The excess of the purchase price over the fair value of the assets
acquired and liabilities assumed was $1,922,000 and $285,000, respectively.
 
  Subsequent to the acquisition, Holdings and ZDI were merged with ZDI being
the surviving corporation.

  The pro forma results include amortization of intangible assets and interest
expense on debt assumed issued to finance the purchase. The pro forma results
are not necessarily indicative of what actually would have occurred if the
acquisition had been completed as of the beginning of the year, nor are they
necessarily indicative of future combined results.
 
 Purchase of MAC Assets
 
  In 1997, ZDI agreed to purchase certain of the MAC Assets for $370,000. The
acquisition will be effected in two tranches; the first of which closed on
October 31, 1997 and the second, which is subject to the successful completion
of an initial public offering of ZD Inc.'s Common Stock (refer to Note 18) or
upon a similar significant external financing. At December 31, 1997, ZDI has
accrued the $370,000 purchase price which has been recorded as a return of
capital.
 
  The acquisitions from MAC described above have been accounted for in a
manner similar to a pooling of interests as all entities involved are under
common control. Accordingly, the accompanying combined financial statements
include the results of operations of the MAC Assets from February 29, 1996.
Throughout these financial statements any reference to ZDI and ZDCF or the
Companies includes ZDI, ZDCF and the MAC Assets from February 29, 1996.
 
 Acquisition of Sendai
 
  On May 8, 1996, ZDI acquired substantially all of the assets and liabilities
of Sendai Publishing Group, Inc., a publisher and distributor of magazines,
books, products and computer services related to the electronic gaming
industry, for approximately $27,500, plus transaction costs. The acquisition
was accounted for as a purchase and accordingly, Sendai's results are included
in the combined financial statements since the date of acquisition. The excess
of the purchase price over assets acquired approximated $33,378. The
operations of Sendai did not have a material effect on the combined results of
operations for the year ended December 31, 1996.
 
 Acquisition of COMDEX
 
  Effective April 1, 1995, Softbank acquired the assets of the COMDEX trade
show business, now part of ZDCF, for approximately $803,000, plus transaction
costs. The acquisition has been accounted for as of April 1, 1995 using the
purchase method of accounting and accordingly COMDEX's results are included in
the combined financial statements since the date of acquisition. The excess of
the purchase price over the fair value of the assets acquired and liabilities
assumed was $849,000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Combination
 
  The combined financial statements include the accounts of ZDI and ZDCF
including, as discussed above, the MAC Assets. All significant transactions
between these entities have been eliminated in combination.
 
  Investments in companies in which ownership interests range from 20 to 50
percent and the Companies have the ability to exercise significant influence
over the operating and financial policies of such companies are accounted for
under the equity method.
 
 Parent Company Financing
 
  As described in Note 18, Softbank announced a Reorganization and a financing
plan which includes a recapitalization of the Companies' debt and equity
structures. Prior to the consummation of the recapitalization transactions,
the Companies are dependent on funding from Softbank. At December 31, 1997,
the Companies had current liabilities which exceeded current assets by
$371,140. To the extent that the Companies are unable to fund their current
obligations as they become due from their operating cash flows, Softbank has
committed to provide additional financing or to restructure existing loan
arrangements at least through February 1999.
 
 Cash and cash equivalents
 
  The Companies consider all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
 Concentration of credit risk
 
  The Companies place its temporary cash investments with high credit quality
financial institutions. At times, such investments may be in excess of
federally insured limits. The Companies have not experienced losses in such
accounts.
 
  The Companies' advertisers and exhibitors include principally customers who
represent a variety of technology companies in the United States and other
countries. The Companies extend credit to their customers and distributors and
historically have not experienced significant losses relating to receivables
from individual customers or groups of customers.
 
 Property and equipment
 
  Property and equipment have been recorded at cost or their estimated fair
value at the date of acquisition. Depreciation is computed using the straight-
line method over the estimated useful lives of the assets which range from
three to thirty years. Leasehold improvements are amortized using the
straight-line method over the service life of the improvement or the life of
the related lease, whichever is shorter. Maintenance and repair costs are
charged to expense as incurred.
 
 Inventories
 
  Inventories, which consist principally of paper, are stated at the lower of
cost or market. Cost is determined on a first-in, first-out basis.
 
 Intangible assets
 
  Intangible assets consist principally of advertising lists, exhibitor
relationships, trademarks and trade names, and goodwill. Amortization of these
assets is computed on a straight-line basis over their estimated useful lives.
Identifiable
 
                                     F-12

          ZDI (ZIFF-DAVIS INC.) AND ZDCF (ZD COMDEX AND FORUMS INC.)
            (WHOLLY-OWNED INDIRECT SUBSIDIARIES OF SOFTBANK CORP.)
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
intangible assets are amortized over a period of 2 to 40 years and goodwill,
which represents the excess of the purchase price over the estimated fair
values of net assets acquired, is amortized over a period of 5 to 40 years
(refer to Note 5). The Companies assess the recoverability of their intangible
assets whenever adverse events or changes in circumstances indicate that
expected future cash flows (undiscounted and without interest charges) may not
be sufficient to support the carrying amount of intangible assets. If
undiscounted cash flows are not sufficient to support the recorded assets, an
impairment is recognized to reduce the carrying value of the intangibles to
estimated recoverable values. The Companies have not experienced any
impairment of its intangible assets.
 
 Revenue recognition
 
  Advertising revenue for the Companies' publications, less agency
commissions, is recognized as income in the month that the related
publications are sent to subscribers or become available for sale at
newsstands.
 
  Circulation revenue consists of both subscription revenue and single copy
newsstand sales. Subscription revenue, less estimated cancellations, is
deferred and recognized as income in the month that the related publications
are sent to subscribers. Newsstand sales, less estimated returns, are
recognized in the month that the related publications become available for
sale at newsstands.
 
  Payments received in advance of trade shows, conferences and seminars are
initially reported on the balance sheet as deferred revenue and are recognized
as income when the events take place.
 
  Revenue generated by market research is recognized when the service is
provided.
 
  On-line revenue, predominantly advertising, is recognized evenly over the
period of the related advertising contract which corresponds to the period of
time the advertising is displayed.
 
 Operating costs and expenses
 
  Cost of production includes the direct costs of producing magazines,
newsletters and training materials, primarily paper, printing and
distribution, and the direct costs associated with organizing, producing and
managing trade shows, seminars, conferences and expositions. Selling, general
and administrative costs include subscriber acquisition costs which are
expensed as incurred. Editorial and product development costs are expensed as
incurred. Product development costs include the cost of artwork, graphics,
prepress, plates and photography for new products.
 
 Foreign currency
 
  The effect of translating foreign currency financial statements into U.S.
dollars is included in the cumulative translation adjustments account in
stockholder's equity. Gains and losses on foreign currency transactions, which
are not significant to operations, have been included in selling, general and
administrative expenses. The Companies have not historically entered into
forward currency contracts.
 
 Other non-operating income
 
  Other non-operating income includes management fee income and the Companies'
equity share of income or loss from joint ventures.
 
 Income taxes
 
  The Companies use the asset and liability approach for financial accounting
and reporting of deferred taxes.

              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
 
 Use of estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements.
Actual results may differ from these estimates.
 
 Fair value of financial instruments
 
  All current assets and liabilities are carried at cost, which approximates
fair value because of the short-term maturity of those instruments. The
recorded amounts of the Companies' long-term debt payable to affiliates also
approximate fair value based upon the current rates available to the Companies
for debt with similar remaining maturities.
 
 Stock-based compensation
 
  The Companies have elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees," to account for stock options.
Effective January 1, 1996, the Companies adopted the disclosure-only
provisions of Statement of Financial Accounting Standard ("SFAS") No. 123,
"Accounting for Stock-Based Compensation."
 
 Earnings per share
 
  Historical earnings per share data have been omitted on the basis that they
are not meaningful due to the insignificant number of shares outstanding.
 
 New Accounting Pronouncements
 
  SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997, will
require the Companies to disclose, in financial statement format, all non-
owner changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments and unrealized gains and losses on securities
available for sale. This statement is effective for fiscal years beginning
after December 15, 1997 and requires presentation of prior period financial
statements for comparability purposes.
 
  SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and
interim financial reports. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
Generally, financial information will be required to be reported on the basis
that is used internally for evaluating segment performance and deciding how to
allocate resources to segments.
 
  SFAS No. 132, "Employer's Disclosure about Pensions and Other Post-
Retirement Benefits," is effective for the year ended December 31, 1998. This
standard revises the disclosure requirements for employers' pension and other
retiree benefits.
 
  The Companies expect to adopt the above statements beginning with their 1998
financial statements.

  Intangible assets primarily relate to the acquisitions of ZDI, COMDEX and
the MAC Assets. As discussed in Note 1, the acquisitions were accounted for
under the purchase method of accounting. As such, purchase price was allocated
to tangible and identifiable intangible assets with the remaining amount being
allocated to goodwill.
 
  Advertising lists, exhibitor relationships and subscriber lists were
recorded at their estimated fair value as determined by an income approach.
Trademarks/trade names were recorded at their estimated fair value using a
relief from royalty approach.
 
  All intangible assets are being amortized using the straight-line method
over their estimated useful lives, up to 40 years. In determining the
estimated useful lives, the Companies considered their competitive position in
the markets in which they operate, the historical attrition rates of
advertisers, subscribers and exhibitors, legal and contractual obligations,
and other factors.
 
  Recoverability of goodwill and intangible assets is assessed at a minimum on
an annual basis. Impairments would be recognized in operating results if a
permanent diminution in value were to occur based upon an undiscounted cash
flow analysis.

8. INCOME TAXES
 
  The Companies have been included in consolidated U.S. federal income tax
returns filed by Softbank, except for operations relating to the MAC Assets
(described in Note 1), which were assets of a separate taxpayer. The tax
expense reflected in the combined statements of operations and tax liabilities
reflected in the combined balance sheet have been prepared on a separate
return basis as though the Companies filed stand-alone income tax returns. No
tax benefit has been recorded for the losses related to the MAC Assets, as
such losses are not available to the Companies.
 
  The Companies and Softbank do not have a tax sharing agreement. Therefore,
no intercompany tax payments have been made and no related intercompany
receivable or payable has been recorded.
 
  Income (loss) before income taxes is attributable to the following
jurisdictions:

  The effective tax rate differs from the federal statutory tax rate primarily
as a result of the Companies' inability to deduct losses of the MAC Assets
prior to the effective date of the purchase. The amortization of nondeductible
goodwill resulted primarily from the stock acquisition of 100% of the stock of
ZDI in 1996.
 
  Following is a summary of the components of the deferred tax accounts at
December 31, 1996 and December 31, 1997:

  As of December 31, 1996 and 1997 the Companies had total deferred tax assets
of $100,891 and $116,963, respectively, and total deferred tax liabilities of
$273,526 and $288,286, respectively. The December 31, 1996 and December 31,
1997 net deferred tax assets are reduced by a valuation allowance of $49,335
and $38,856, respectively, primarily relating to tax benefits of foreign net
operating loss carryforwards which are not expected to be realized. The
decrease in the valuation allowance in 1997 is primarily related to the
expiration of foreign net operating loss carryforwards. No deferred tax asset
has been established for the losses associated with the MAC Assets, which will
not be available to the Companies as a deduction.
 
  The Companies have U.S. and foreign net operating loss carryforwards of
approximately $286,322, which will begin to expire in 1998. The Companies'
utilization of certain net operating loss carryforwards, of approximately
$122,549, is subject to limitations, due to the change of ownership resulting
from the Softbank

acquisition of the ZDI stock on February 29, 1996. Management believes that
such limitations will not significantly affect the Companies' ability to
recognize the deferred tax assets relating to the carryforward. Accordingly,
no valuation allowance to reduce the deferred tax asset relating to the
carryforward has been established. In addition, the Companies have alternative
minimum tax credit carryforwards of $385 which may be carried forward
indefinitely until used.
 
  The Companies' foreign subsidiaries have no undistributed earnings for
remittance to the U.S. and, therefore, no U.S. or foreign tax provision on
remittances has been recorded.

  The Companies are members of a group of companies affiliated through common
ownership with Softbank and has various transactions and relationships with
members of the group. Because of these relationships, it is possible that the
terms of those transactions are not the same as those that would result from
transactions among unrelated parties.

  See Note 18 for a discussion of the Companies' plan to restructure their
debt and equity structures.
 
  As part of the 1996 acquisition of ZDI, the Companies agreed to assume
certain obligations to management arising out of prior employment arrangements
with previous owners. In January 1997, the Companies paid all amounts due,
including accrued interest, through the payment date.
 
  Periodically, the Companies transfer excess cash to Softbank for cash
management purposes and in turn receive cash advances from Softbank to fund
the Companies' short-term working capital requirements. Interest is accrued
based on the net balance outstanding at the end of each month. Interest income
is earned at the 30-day LIBOR rate for the applicable month. Interest expense
is incurred at the 30-day LIBOR rate plus 0.5%.

 Other affiliated arrangements
 
  During the years ended December 31, 1996 and 1997, the Companies incurred
$2,000 and $1,631, advertising expense with Yahoo!, Inc. (Yahoo!), an
affiliated company. No advertising expense with Yahoo! was incurred in 1995.
 
  The Companies sell advertising space and exhibition services to Kingston
Technology Company ("Kingston"), an affiliated company. During the years ended
December 31, 1995, 1996 and 1997, the Companies recorded revenues of $0, $882
and $2,667, respectively, from sales to Kingston. These services were provided
under terms consistent with those provided to unaffiliated customers.
 
  ZDCF has entered into an agreement to manage certain trade shows and
expositions owned by Softbank and its affiliates, whereby ZDCF earns
management and licensing fees. The fees earned by ZDCF for the years ended
December 31, 1995, 1996 and 1997 were $1,979, $3,394 and $4,057, respectively.
 
  In 1996 and 1997, the Companies had an arrangement with SOFTBANK Interactive
Marketing ("SIM"), an affiliated company, for the provision of interactive
media sales. The Companies paid commissions to SIM of $600 and $1,800 during
the years ended December 31, 1996 and 1997, respectively. Effective December
31, 1997, SIM was acquired by an unrelated third party. Management believes
that the sale of SIM by Softbank will have no material impact on the
Companies.
 
  The Companies have an arrangement with SOFTBANK Services, an affiliated
company, whereby the Companies are charged for administrative services
provided plus a management fee. For the years ended December 31, 1995, 1996
and 1997, the Companies incurred services fees of $0, $359 and $1,259,
respectively, in relation to this agreement.
 
  ZDI has entered into certain licensing agreements with Softbank for the
publishing and distribution of Japanese language editions of certain
publications. The fees earned by ZDI for the years ended December 31, 1996 and
1997 were approximately $964 and $1,818, respectively, in each year.
 
  The Companies have entered into a license and services agreement with MAC to
develop ZDTV: Your Computer Channel. ZDTV is owned by MAC, but as part of this
license and services agreement MAC has granted the Companies an option
exercisable through December 31, 1998 to purchase all of MAC's interest in
ZDTV for an amount equal to MAC's investment plus 10% per annum. The Companies
are currently funding ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. Such advances bear interest at the 30-day LIBOR rate plus .50%. The
Companies' cumulative advances, which totaled $14.4 million net of $10.1
million in repayments through December 31, 1997, will be repaid concurrently
with the Reorganization (See Note 18). The Companies have not yet determined
whether they will exercise the option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon access to sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Companies. ZDTV is not included in the
Companies' financial statements.
 
  If the Companies were to acquire a controlling interest in ZDTV from MAC,
such acquisition would be accounted for as a pooling transaction; if the
Companies were to acquire a non-controlling interest, such acquisition would
be accounted for under the equity method.
 
  ZDI has entered into operating leases for television production equipment
and has sublet such equipment to ZDTV, an affiliated company. The terms of the
subleases are substantially identical to the terms of the leases which provide
for annual lease payments totaling approximately $610 through 2003.

 Guarantee of Softbank's U.S. debt
 
  In April 1996, Softbank signed a line of credit agreement totaling $50,000
with an independent lender for which the Companies, along with certain other
Softbank affiliates, are guarantors. In January 1997 and October 1997, this
line of credit was increased to $75,000 and $150,000, respectively. At
December 31, 1997, $102,500 was outstanding under the line of credit.
 
 Return of capital and dividends
 
  On December 15, 1996, the Companies declared a return of capital of
approximately $900,000 paid through the issuance of a note payable to a
subsidiary of Softbank and a cash dividend of $8,000 to Softbank. In 1997, the
Companies recorded a return of capital of $381,434 in connection with the
purchase price of companies under common control.

10. EMPLOYEE STOCK COMPENSATION PLANS
 
 Executive stock option plan
 
  The SOFTBANK 1996 and 1997 Executive Stock Option Plans provide for the
granting of nonqualified stock options to purchase the common stock of
Softbank to officers, directors and key employees of the Companies. Under the
plans, options have been granted at exercise prices equal to the closing
market price in Japan's public equities market (market price denominated in
Japanese yen) on the date of grant. As of December 31, 1997, substantially all
options granted become exercisable in various installments over the first six
anniversaries of the date of grant and expire ten years after the date of
grant.

(1) The exercise price of the stock options is set in Japanese yen. The
    exercise prices as shown above have been converted to U.S. dollars based
    upon the exchange rate as of the date of grant for the respective options.
(2) Adjusted for a 1.4:1 stock split during 1996 and a 1.3:1 stock split
    during 1997.
 
  As permitted by SFAS 123, the Companies have chosen to continue to account
for stock options in accordance with the provisions of APB 25 and,
accordingly, no compensation expense related to stock option grants was
recorded in 1996 or 1997. Pro forma information regarding net income is
required by SFAS 123 and has been determined as if the Companies had accounted
for stock options under the fair value method. The fair value of the option
grants was estimated at the date of grant using the Black Scholes option-
pricing model with the following assumptions for 1996 and 1997:

  The weighted average fair value of options granted in 1996 and 1997 was
$64.30 and $34.05, respectively. For purposes of the pro forma disclosures,
the estimated fair value of the options is amortized to expense over

the options' vesting period. Had compensation cost for the stock option plans
been determined based upon the fair value at the grant date for awards during
1996 and 1997, consistent with the provisions of SFAS 123, the Companies' net
loss would have been increased by approximately $3,100 and $4,200,
respectively. On January 23, 1998, the exercise price of all of the shares
outstanding under option agreements were reset to an exercise price equal to
the closing market price on Japan's Tokyo Stock Exchange First Section at that
date. In conjunction with the repricing, those options previously exercisable
on December 31, 1997 may now be exercised only after July 19, 1998. Repricing
of the stock options will not result in compensation expense to the Companies.
 
 Other stock compensation plans
 
  During 1996 and 1997, the Company granted 45,760 and 61,940 shares of common
stock of Softbank, respectively, (adjusted for two 1.4:1 stock splits during
1996 and a 1.3:1 stock split during 1997) to certain key employees, subject to
restrictions as to continuous employment which expire over a three to five-
year period from the date of grant. The granting of the shares to the
Companies' employees has been recorded as additional paid-in capital offset by
a reduction to stockholder's equity as deferred compensation. Such amounts
were recorded at the fair value, as established by market price of the shares
on the date of grant. The unearned compensation is being amortized ratably
over the restricted periods. During 1996, restrictions on 13,790 shares
expired, 2,160 shares were forfeited and $1,080 was charged to expense related
to the restricted stock awards. During 1997, restrictions on 75,210 shares
expired, 2,150 shares were forfeited and $3,916 was charged to expense related
to these restricted stock awards.
 
11. EMPLOYEE BENEFIT PLANS
 
 Pension plan
 
  Certain employees of ZDCF who have met eligibility requirements are covered
by a noncontributory defined benefit pension plan. The benefits are based on
years of service and average compensation at the time of retirement. The
Companies' funding policy is to contribute amounts sufficient to meet the
minimum funding requirements as set forth in the Employee Retirement Income
Security Act of 1974 ("ERISA"). Contributions to the plan are determined in
accordance with the projected unit credit cost method. Plan assets consist of
U.S. equity securities, high grade corporate bonds and commercial paper, and
U.S. treasury notes.
 
  The weighted average assumed discount rate of 7% and rate of increase in
future compensation levels of 6% was used in the determination of the
actuarial present value of the projected benefit obligation at December 31,
1996 and 1997. The weighted average expected long-term rate of return on plan
assets at December 31, 1996 and 1997 was 7%.
 
  Net periodic pension cost includes the following components:

also make contributions to the plan in which they participate which, and
subject to certain limitations, may be matched by the Companies up to certain
specified percentages. Employees are generally eligible to participate in a
plan upon joining the Companies and receive matching contributions after one

18. SUBSEQUENT EVENTS (UNAUDITED)
 
 Reorganization of the Companies
 
  In February 1998, Softbank announced a reorganization of the Companies (the
"Reorganization"). In connection with the Reorganization, Softbank will
contribute the common stock of ZDI and ZDCF to a newly formed company in
exchange for a majority of the new company's common stock, the balance of
which will be offered to the public. In addition, approximately $928 million
of obligations owed to Softbank will be converted to equity, approximately
$1.5 billion of notes payable to affiliates will be refinanced, the $370
million obligation for the purchase of the MAC Assets will be paid and
balances totaling approximately $42 million due from MAC will be settled. The
Reorganization is contingent upon the successful completion of the public
stock offering and refinancing of the notes payable to affiliates.
 
 Guarantee of Softbank's U.S. Debt
 
  In March 1998, the Company increased its guarantee of Softbank's U.S. debt
from $150 million to $450 million.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, cash flows and changes in stockholder's
equity, present fairly, in all material respects, the financial position of
Ziff-Davis Inc. and its subsidiaries (formerly Ziff-Davis Publishing Company
or the "Company") at December 31, 1995 and February 28, 1996, and the results
of their operations and their cash flows for the year ended December 31, 1995
and for the period from January 1, 1996 to February 28, 1996, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.
 
As discussed in Note 16 to the financial statements, the Company was acquired
by SOFTBANK Holdings Inc. on February 29, 1996.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
1. ORGANIZATION AND ACQUISITION
 
  Ziff-Davis Inc. ("ZDI," formerly Ziff-Davis Publishing Company) is a wholly-
owned subsidiary of Ziff-Davis Holdings Corp. ("Holdings").
 
  ZDI is engaged in publishing magazines, journals and training manuals and
providing market research about the computer industry, with operations in the
United States, Canada and Europe.
 
 Acquisition
 
  Effective January 1, 1995, Holdings, through ZDI, directly and indirectly
acquired certain assets and assumed certain liabilities of the Ziff-Davis
publishing business and related businesses (the "Acquisition" or the "Acquired
Businesses") from Ziff Communications Company, L.P., a limited partnership
("ZCC") and other persons and entities (collectively referred to as the
"Sellers"), for an aggregate purchase price of approximately $1,400,000 plus
transaction costs. ZDI funded the Acquisition through the issuance of Common
Stock, bank borrowings and a subordinated note payable to Holdings.
 
  The acquisition has been accounted for using the purchase method of
accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of ZDI and its
subsidiaries. All significant intercompany accounts and transactions have been
eliminated in consolidation.
 
  Investments in companies in which ownership interests range from 20 to 50
percent are accounted for under the equity method. ZDI has an equity
investment interest in Family PC G.P. of 50%. The equity investment in Family
PC G.P. is not material to ZDI's consolidated financial statements.
 
 Cash and cash equivalents
 
  ZDI considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents.
 
 Concentration of credit risk
 
  ZDI places its temporary cash investments with high credit quality financial
institutions. At times, such investments may be in excess of federally insured
limits. ZDI has not experienced losses in such accounts.
 
  ZDI's advertisers include customers who represent a variety of technology
companies in the United States and other countries. ZDI extends credit to its
customers and historically has not experienced significant losses relating to
receivables from individual customers or groups of customers.
 
 Property and equipment
 
  Property and equipment have been recorded at their estimated fair value at
the date of acquisition. Depreciation is computed using the straight-line
method over the estimated useful lives of the acquired assets, ranging from 3
to 39 years. Leasehold improvements are amortized using the straight-line
method over the service life of the improvement or the life of the related
lease, whichever is shorter. Maintenance and repair costs are charged to
expense as incurred.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
 Paper inventories
 
  Paper inventories are stated at the lower of cost or market. Cost is
determined on a first-in, first-out basis.
 
 Intangible assets
 
  Intangible assets consist principally of advertising lists, trademarks and
trade names and goodwill. Amortization of these assets is computed on a
straight-line basis over their estimated useful lives. Identifiable intangible
assets are amortized over a period of 2 to 39 years and goodwill, which
represents the excess of the purchase price over the estimated fair values of
net assets acquired, is amortized over 40 years. ZDI assesses the
recoverability of its intangible assets whenever adverse events or changes in
circumstances indicate that expected future cash flows (undiscounted and
without interest charges) may not be sufficient to support the carrying amount
of intangible assets. If undiscounted cash flows are not sufficient to support
the recorded assets, an impairment loss is recognized to reduce the carrying
value of the intangibles to its estimated recoverable value.
 
 Revenue recognition
 
  Advertising revenue for ZDI's publications, less agency commissions, is
recognized as income in the month that the related publications are sent to
subscribers or becomes available for sale at newsstands.
 
  Circulation revenue consists of both subscription and single copy newsstand
sales. Subscription revenue, less estimated cancellations, is deferred and
recognized as income in the month that the related publications are sent to
subscribers. Newsstand sales, less estimated returns, are recognized in the
month that the related publications become available for sale at newsstands.
 
  Revenue generated by market research is recognized when the service is
provided.
 
 Operating costs and expenses
 
  Cost of production includes paper, manufacturing, distribution and
fulfillment. Selling and promotion costs include subscriber acquisition costs
which are expensed as incurred. Editorial and product development costs are
generally expensed as incurred. Product development costs include the cost of
artwork, graphics, prepress, plates and photography for new products.
 
 Foreign currency
 
  Gains and losses on foreign currency transactions, which are not
significant, have been included in selling, general and administrative
expenses. The effect of translation of foreign currency financial statements
into U.S. dollars is included in the cumulative translation adjustments
account in stockholder's equity.
 
 Income taxes
 
  ZDI uses the asset and liability approach for financial accounting and
reporting of deferred taxes.
 
 Use of estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements.
Actual results may differ from these estimates.

 Fair value of financial instruments
 
  All current assets and liabilities are carried at cost, which approximates
fair value because of the short-term maturity of those instruments. The
recorded amounts of ZDI's long-term debt also approximate fair value which was
based upon the current rates available to ZDI for debt with similar remaining
maturities.
 
 Impairment of long-lived assets
 
  In 1995, the Financial Accounting Standards Board issued SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to be Disposed Of" ("SFAS 121"). ZDI adopted SFAS 121 in fiscal 1996 with no
effect on operations.
 
 Earnings per share
 
  Historical earnings per share data has been omitted on the basis that it is
not meaningful due to the insignificant number of shares outstanding.

</TABLE>
 
  Intangible assets primarily relate to the acquisition of ZDI. As discussed
in Note 1, the acquisition was accounted for under the purchase method of
accounting. As such the purchase price was allocated to tangible and
identifiable intangible assets with the remaining amount allocated to
goodwill.
 
  Advertising lists, exhibitor relationships and subscriber lists were
recorded at their estimated fair value as determined by an "income" approach.
Trademarks/trade names were recorded at their estimated fair value using a
"relief from royalty" approach.
 
  All intangible assets are being amortized using the straight-line method
over their estimated useful lives, up to 40 years. In determining the
estimated useful lives, ZDI considered its competitive position in the markets
in which it operates, the historical attrition rates of advertisers,
exhibitors and subscribers, legal and contractual obligations, and other
factors.
 
  Recoverability of goodwill and intangible assets is assessed at a minimum on
an annual basis. Impairments would be recognized in operating results if a
permanent diminution in value were to occur based upon an undiscounted cash
flow analysis.

carryforwards of approximately $244,172, which will begin to expire on
December 31, 1996. The December 31, 1995 and the February 28, 1996 net
deferred tax asset is reduced by a valuation allowance of $47,176 relating to
tax benefits of foreign net operating loss carryforwards which are not
expected to be recognized.
 
  ZDI's foreign subsidiaries have no undistributed earnings for remittance to
the U.S. and therefore no U.S. or foreign tax provision on remittances has
been recorded.

</TABLE>
 
  On December 21, 1994, ZDI borrowed $515,000 under the terms of a Credit
Agreement. The proceeds of the loan were used to finance a portion of the
Acquisition and pay certain transaction costs.
 
  Tranche A, as amended on August 31, 1995, is a six-year term loan due
quarterly in varying amounts from September 30, 1995 through December 31,
2000. Tranche B is a seven-year term loan due quarterly in varying amounts
commencing September 30, 1995 through September 30, 2001, with a final payment
of $126,000 on December 31, 2001. Tranche C is an eight-year term loan
providing for quarterly payments, aggregating $1,000 per calendar year
commencing September 30, 1995 through December 31, 2001, followed by four
quarterly payments of $39,500 through December 31, 2002.
 
  The Credit Agreement also provides ZDI with an additional $85,000, increased
to $150,000 under terms of the August 31, 1995 amendment, under a revolving
credit arrangement through December 31, 2000. These funds are available for
loans, letters of credit, and swing-line loans, subject to certain maximum
levels of borrowing. At least once during each year, for a period of 30
consecutive days, the loans outstanding under the revolving credit facility
must be reduced so that the aggregate outstanding amount does not exceed
$130,000 during such 30-day period. The commitment fee for the revolving
credit facility is .50% during 1995 and 1996 on the unused portion of the
facility. ZDI has the option to permanently reduce the amount available for
borrowings under the revolving credit facility by a minimum of $5,000 at any
time. At December 31, 1995 and February 28, 1996, $130,000 under the revolving
credit facility is available for borrowing.
 
  During 1995 and the period January 1, 1996 to February 28, 1996, the Tranche
A and revolving credit loans bore interest, payable at least quarterly, at
either the Average Bank Rate ("ABR"), as defined, plus 1.25%, or at the
Eurodollar rate, plus 2.5% at the election of ZDI. Tranche B and C loans bore
interest, payable at least quarterly, at either the ABR, plus 1.75% and 2.25%,
respectively, or at the Eurodollar rate, as defined, plus 3% and 3.5%,
respectively, at the election of ZDI. Swing-line loans bear interest at the
ABR, plus the applicable margins as discussed above. Borrowings outstanding at
December 31, 1995 and February 28, 1996 were $446,000 and the weighted average
interest rate was 8.8% and 10.1%, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

  ZDI is required to comply with various restrictive covenants, including
maintaining certain financial ratios, restrictions on additional indebtedness,
capital expenditures, acquisitions, certain asset sales, declaration of
dividends and acquisition of ZDI's or Holdings' Common Stock. All borrowings
under the Credit Agreement are secured by the common stock and other equity
interests of ZDI and its wholly-owned subsidiaries.
 
  ZDI is required to make mandatory prepayments of the loans with the net
proceeds of certain asset sales and debt issuances, if any. ZDI is also
required, commencing with the year ending December 31, 1995, to prepay the
loans with a portion of excess cash flow, as defined, once certain cash
balances are achieved. These cash balances were not achieved during 1995 or
for the period from January 1, 1996 to February 28, 1996 and therefore no
prepayments occurred.
 
  Scheduled principal payments for each of the next five years are as follows:

10. RELATED PARTY TRANSACTIONS
 
  Prior to the Acquisition, ZCC provided certain services to ZDI, including
legal, tax, human resources, payroll, facilities management and management
information services. The remaining unpaid balance (approximately $8,100) for
such services was paid in the normal course of business during 1995. Beginning
in 1995, ZDI sublet office space and provided administrative services to ZCC.
Such office space and services were provided to ZCC at ZDI's cost. The
majority partners of ZCC have a continuing investment in Holdings of
approximately 6%.
 
  On the closing date of the Acquisition, ZDI paid approximately $280,000 in
cash to the Sellers and issued notes due January 13, 1995 and January 16, 1995
totaling $1,033,931, for the balance. These notes were subsequently fully paid
in January, 1995.
 
  See Note 11 for a description of subordinated debentures.
 
  In connection with the Acquisition, ZDI paid transaction costs of $14,000 to
an affiliate of Holdings.
 
  The Company paid $44,555 and $3,791 in interest to Holdings for the year
ended December 31, 1995 and for the period from January 1, 1996 to February
28, 1996, respectively.
 
11. SUBORDINATED DEBENTURES--RELATED PARTY
 
  On December 21, 1994, ZDI issued a $525,000 subordinated note payable to
Holdings to finance a portion of the Acquisition. The note bears interest at 8
1/2% per annum with interest payable semiannually on February 28 and August 31
of each year. The principal is repayable in three installments of $175,000
each on December 21, 2005, December 21, 2006 and December 21, 2007. This note
is fully subordinated in right of payment to the bank borrowings (see Note 9).

12. EMPLOYEE BENEFIT PLANS
 
 Retirement plans
 
  ZDI and its subsidiaries maintain various defined contribution retirement
plans. Substantially all of ZDI's employees are eligible to participate in one
of the plans under which annual contributions may be made by ZDI for the
benefit of all eligible employees. Employees may also make contributions to
the plan in which they participate which, subject to certain limitations, may
be matched by ZDI up to certain specified percentages. Employees are generally
eligible to participate in a plan upon joining ZDI and receive matching
contributions immediately upon commencement of employment. In addition, the
employees become eligible to receive a discretionary Company contribution
after one year of employment. ZDI made contributions of $8,432 and $1,407 for
the year ended December 31, 1995 and for the period ended February 28, 1996,
respectively.
 
13. SALE OF BUSINESSES
 
  During 1995, ZDI disposed of two subsidiaries and received cash
consideration of $23,508. No gain or loss was realized on the dispositions.
 
14. OPERATING LEASE COMMITMENTS
 
  ZDI is obligated under various operating leases which expire at various
dates through 2006. Future minimum rental commitments under noncancelable
operating leases are as follows:

</TABLE>
 
  Netted in the above totals is approximately $2,300 for which ZDI has
noncancelable subleases in place. Total sublease income approximates ZDI's
required payments under the related leases. Rent expense amounted to
approximately $22,900 and $4,020 for the year ended December 31, 1995 and for
the period from January 1, 1996 to February 28, 1996, respectively.
 
15. CONTINGENCIES
 
  ZDI is subject to various claims and legal proceedings arising in the normal
course of business. Management believes that the ultimate liability, if any,
in the aggregate will not be material to the consolidated balance sheet,
future operations or cash flows.
 
16. SUBSEQUENT EVENTS
 
 Acquisition of the Company
 
  In February 1996, SOFTBANK Corp. entered into an agreement to acquire the
stock of ZDI for an aggregate purchase price of approximately $1,800,000, plus
transaction costs. In a separate agreement, MAC Inc. Ltd., an affiliated
company of SOFTBANK Corp., acquired directly and through affiliates, certain
of the assets and assumed certain of the liabilities of ZDI for an aggregate
purchase price of approximately $302,000.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees
and individuals against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with any threatened, pending or completed actions, suits or
proceeding in which such person is made a party by reason of such person being
or having been a director, officer, employee or agent to the Registrant. The
statute provides that it is not exclusive of other rights to which those
seeking indemnification may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise. Section 6.4 of the
Registrant's By-laws provides for indemnification by the Registrant of its
directors, officers and employees to the fullest extent permitted by the
Delaware General Corporation Law.
 
  Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for payments of unlawful dividends or unlawful stock repurchases or
redemptions, or (iv) for any transaction from which the director derived an
improper personal benefit. The Company's Certificate of Incorporation provides
for such limitation of liability.
 
  Reference is also made to Section 7(c) of the Underwriting Agreement filed
as Exhibit 1.1 to the Registration Statement for information concerning the
Underwriters' obligation to indemnify the Registrant and its officers and
directors in certain circumstances.

ITEM 17. UNDERTAKINGS
 
  (a) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing of the Offering, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under "Item 14,
Indemnification of Directors and Officers" above, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment to the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
  (c) The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 424(b)(1) or (4) or 497(h)
  under the Securities Act shall be deemed to be part of this Registration
  Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

462(b) under the Securities Act) and any documents in connection therewith,
and to file the same with the Securities and Exchange Commission, each of said
attorneys-in-fact to have power to act with or without the other, and to have
full power and authority to do and perform, in the name and on behalf of each
such officer and director of the Registrant who shall have executed such a
power of attorney, every act whatsoever which such attorneys-in-fact, or any
of them, may deem necessary or desirable to be done in connection therewith as
fully and to all intents and purposes as such officer or director of the
Registrant might or could do in person.

outstanding shares entitled to vote, irrespective of the provisions of Section
242(b)(2) of the General Corporation Law of Delaware or any corresponding
provision hereafter enacted.

                                 ARTICLE FIFTH

                                    BY-LAWS

          The board of directors of the Corporation is expressly authorized to
adopt, amend or repeal by-laws of the Corporation.

          The by-laws of the Corporation may also be altered or repealed and new
by-laws may be adopted (i) at any annual or special meeting of stockholders, by
the affirmative vote of the holders of not less than a majority of the voting
power of all outstanding shares of capital stock of the Corporation entitled to
vote generally in the election of directors, considered for purposes hereof as a
single class, provided, however, that any proposed alteration or repeal of, or
the adoption of any by-law inconsistent with, Sections 1.2, 1.11 and 1.12 of
Article I of the by-laws, Sections 2.1 and 2.2 of Article II of the by-laws, or
this sentence, by the stockholders shall require the affirmative vote of the
holders of not less than 80% of the voting power of all outstanding shares of
capital stock of the Corporation entitled to vote generally in the election of
directors, considered for purposes hereof as a single class, or (ii) by the
affirmative vote of a majority of the board of directors.

                                 ARTICLE SIXTH

                               BOARD OF DIRECTORS

          The number of directors of the Corporation shall be fixed from time to
time pursuant to the by-laws of the Corporation.  Commencing with the first
annual meeting of stockholders, the directors of the Corporation shall be
divided into three classes, as nearly equal in number as reasonably possible, as
determined by the board of directors, with the initial term of office of the
first class of such directors ("Class I") to expire at the first annual meeting
of stockholders, the initial term of office of the second class of such
directors ("Class II") to expire at the second annual meeting of stockholders
and the initial term of office of the third class of such directors ("Class
III") to expire at the third annual meeting of stockholders thereafter, with
each class of directors to hold office until their successors have been duly
elected and qualified.  At each annual meeting of stockholders, directors
elected to succeed the directors whose terms expire at such annual meeting shall
be elected to hold office for a term expiring at the annual meeting of
stockholders in the third year following the year of their election and until
their successors have been duly elected and qualified.  Elections of directors
need not be by written ballot except and to the extent provided in the by-laws
of the Corporation.  In the event of any increase or decrease in the authorized
number of directors, (a) each director then serving as such shall nonetheless
continue as a director of the class of which he is a member until the expiration
of his current term, or his earlier death, retirement, resignation, or removal,
and (b) the newly created or eliminated directorships resulting from such
increase or decrease shall be apportioned by the board of directors among the
three classes of directors so as to maintain such classes as nearly equal in
number as reasonably possible.  No director may be removed except for cause,
provided a director who is also an officer of the Corporation shall resign or be
removed upon termination of his or her employment as such officer.  This Article
SIXTH may not be amended, modified or repealed except by the affirmative vote of
the holders of not less than 80% of the voting power of all outstanding shares
of capital stock of the Corporation entitled to vote generally in the election
of directors, considered for purposes hereof as a single class.

                               STOCKHOLDER ACTION

          Any action required or permitted to be taken by the stockholders of
the Corporation must be taken at a duly called annual or special meeting of such
holders and may not be taken by any consent in writing by such holders.  Except
as otherwise provided for herein or required by law, special meetings of
stockholders of the Corporation for any purpose or purposes may be called only
by the Chairman or the board of directors pursuant to a resolution stating the
purpose or purposes thereof, and any power of stockholders to call a special
meeting is specifically denied.


                                 ARTICLE EIGHTH

                               DIRECTOR LIABILITY

          A director of the Corporation shall not be liable to the Corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except to the extent that such exemption from liability or limitation
thereof is not permitted under the Delaware General Corporation Law as currently
in effect or as the same may hereafter be amended.  No amendment, modification
or repeal of this Article EIGHTH shall adversely affect any right or protection
of a director that exists at the time of such amendment, modification or repeal.

and shall specify (A) the requested date for the making of the requested RC
Loan, which shall be, in the case of a Base Rate RC Loan, a Business Day and, in
the case of a Eurodollar Rate RC Loan, a Eurodollar Business Day, (B) the Type
or Types of RC Loans requested and (C) the amount of each such Type of RC Loan,
the aggregate of which amounts for each Type of RC Loans requested shall,
subject to Section 1.10(b)(ii), be not less than (1) in the case of Eurodollar
Rate RC Loans, the lesser of (aa) $10,000,000 or any integral multiple of
$1,000,000 in excess thereof and (bb) the aggregate amount of unused RC
Commitments and (2) in the case of Base Rate RC Loans, the lesser of (aa)
$1,000,000 or any integral multiple of $500,000 in excess thereof, and (bb) the
aggregate amount of the unused RC Commitments.  Upon receipt of any such notice,
the Administrative Agent shall promptly notify each Bank of the contents thereof
and the amount and Type of RC Loan to be made by such Bank.

          (ii) On each requested date for the making of RC Loans, each Bank
shall, if it has received the notice contemplated by Section 1.02(a)(i) on or
prior to (A) in the case of Eurodollar Rate Loans, its close of business on the
third Eurodollar Business Day before such requested date and (B) in the case of
Base Rate Loans, its close of business on the Business Day before such requested
date, make available to the Administrative Agent, not later than 11:00 a.m., in
Dollars in funds immediately available to the Administrative Agent at the
Administrative Agent's Office, the RC Loans to be made by such Bank on such
requested date.  Any Bank's failure to make any RC Loan to be made by it on the
requested date therefor shall not relieve any other Bank of its obligation to
make any RC Loan to be made by such other Bank on such date, but such other Bank
shall not be liable for such failure.

          (iii) Unless the Administrative Agent shall have received notice from
a Bank prior to 10:00 a.m., on the requested date for the making of any RC Loans
that such Bank will not make available to the Administrative Agent the RC Loans
requested to be made by such Bank on such date, the Administrative Agent may
assume that such Bank has made such RC Loans available to the Administrative
Agent on such date in accordance with Section 1.02(a)(ii) and the Administrative
Agent in its sole discretion may, in reliance upon such assumption, make
available to the Borrower (or, in the case of RC Loans requested pursuant to
Section 1.04(d) or Section 1.05(b)(i), to the Swing Line Bank) on such date a
corresponding amount on behalf of such Bank.  If and to the extent such Bank
shall not have so made available to the Administrative Agent the RC Loans
requested to be made by such Bank on such date and the Administrative Agent
shall have so made available to the Borrower a corresponding amount on behalf of
such Bank, such Bank shall, on demand, pay to the Administrative Agent such
corresponding amount 

                                       2

together with interest thereon, for each day from the date such amount shall
have been so made available by the Administrative Agent to the Borrower until
the date such amount shall have been repaid to the Administrative Agent, at the
Federal Funds Rate until (and including) the third Business Day after demand is
made and thereafter at the Base Rate. If such Bank does not pay such
corresponding amount promptly upon the Administrative Agent's demand therefor,
the Administrative Agent shall promptly notify the Borrower and the Borrower
shall immediately repay such corresponding amount to the Administrative Agent
together with accrued interest thereon at the applicable rate or rates
provided in Section 1.03(a); provided that no such repayment by the Borrower
                             --------                                       
shall affect the rights of the Borrower with respect to any Bank's wrongful
refusal to lend.

          (iv) All RC Loans made available to the Administrative Agent in
accordance with Section 1.02(a)(ii) shall be disbursed by the Administrative
Agent not later than 2:00 p.m. on the requested date therefor in Dollars in
funds immediately available to the Borrower by credit to an account of the
Borrower at the Administrative Agent's Office or in such other manner as may
have been specified in the applicable notice and as shall be acceptable to the
Administrative Agent.

               (iii)  Post-Default Rate.
                      ----------------- 

          During an Event of Default (which is such by virtue of clause (a) of
Section 6.01, and whether before or after judgment), each Loan (whether or not
due) and, to the maximum extent permitted by Applicable Law, all other amounts
in respect of interest and fees due and payable under the Borrower Loan
Documents, shall bear interest at a rate per annum equal to the applicable Post-
Default Rate.

          (b)  Payment.

Loan shall continue as a Base Rate Loan unless and until such Loan is converted
into a Term A Loans, Term B Loan or an RC Loan, as the case may be, of another
Type.  Each Term A Loans, Term B Loan and RC Loan that is a Eurodollar Rate Loan
of any Type shall continue as a Term A Loans, Term B Loan or an RC Loan, as the
case may be, of such Type until the end of the then current Interest Period
therefor, at which time it shall be automatically converted into a Base Rate
Loan unless the Borrower shall have given the Administrative Agent notice in
accordance with Section 1.03(c) requesting either that such Loan continue as a
Loan of such Type or that such Loan be converted into a Term A Loans, Term B
Loan or an RC Loan, as the case may be, of another Type at the end of such

<PAGE>
 
          (iii) Notwithstanding anything to the contrary contained in Section
1.03(c)(i) or (ii), during a Default, the Administrative Agent may notify the
Borrower that Term A Loans, Term B Loans and RC Loans may only be converted into
or continued as Term A Loans, Term B Loans and RC Loans, as the case may be, of
certain specified Types and, thereafter, until no Default shall continue to
exist, Term A Loans, Term B Loans and RC Loans may not be converted into or
continued as Term A Loans, Term B Loans or RC Loans of any Type other than one
or more of such specified Types.

          (iv) The Borrower shall give the Administrative Agent notice (which

Eurodollar Rate Loan, 11:00 a.m. on the third Eurodollar Business Day before,
the requested date of such conversion or continuation.  Each notice of
conversion or continuation shall be in the form of Schedule 1.03(c) and shall
                                                   ----------------

               --------------------- 

          Nothing contained in the Loan Documents shall require the Borrower at
any time to pay interest at a rate exceeding the Maximum Permissible Rate.  If
interest payable by the Borrower on any date would exceed the maximum amount
permitted by the Maximum Permissible Rate, such interest payment shall
automatically be reduced to such maximum permitted amount, and interest for any
subsequent period, to the extent less than the maximum amount permitted for such
period by the Maximum Permissible Rate, shall be increased by the unpaid amount
of such reduction.  Any interest actually received for any period in excess of
such maximum amount permitted for such period shall be deemed to have been
applied as a prepayment of the Loans, the Drawings or the other amounts in
respect of which such interest was paid, as the case may be.

either an RC Loan pursuant to Section 1.02(a) hereof or a Swing Loan pursuant to

          (b) Default Mandatory Prepayments and Fundings.
              ------------------------------------------ 

(i)  Default Mandatory Prepayments of Swing Loans.
     -------------------------------------------- 

          If any Default exists, other than a Bankruptcy Default, the Swing Line
Bank may request that outstanding Swing Loans be refunded by delivering to the
Administrative Agent and the Borrower on any Business Day a request to that
effect, specifying the principal amount of outstanding Swing Loans.  Such a

notice from the Borrower under such Section and (C) be subject to all the terms
and conditions of Section 1.02(a), except that (1) the requirement (aa) to
deliver a notice in the form of Schedule 1.02(a) and (bb) that the aggregate
                                ----------------

Swing Loans then outstanding) by the Swing Line Bank on any Business Day, each
Bank (including the Swing Line Bank in its capacity as a Bank) shall purchase
from the Swing Line Bank, without recourse or warranty (except that such
outstanding Swing Loans in fact were made in accordance with Section 1.01(d)(i),
and are not subject to any Liens arising out of any act of the Swing Line Bank),
a participation in the Swing Loans then outstanding (each such participation a
"Swing Loan Participation") by paying to the Swing Line Bank, in Dollars
- -------------------------                                               
immediately available to the Swing Line Bank at the Swing Line Bank's Office, an
amount equal to such Bank's Pro Rata Share of the principal amount of such Swing
Loans, with such payment being due on the day such request is made, if such
request is made prior to 2:00 p.m. on such day, or if such request is made after
2:00 p.m. on the next Business Day (the "Participation Payment Date").  Each
                                         --------------------------         
Swing Loan Participation shall constitute an undivided interest and
participation in the principal amount of Swing Loans then outstanding and in
interest that accrues thereon after the Participation Payment Date.  The Swing
Line Bank shall, upon the request of a Bank, furnish to such Bank a
participation certificate evidencing any Swing Loan Participation purchased by
such Bank pursuant to this Section 1.05.  If any Bank does not pay when due any
amount which it is required to pay to the Swing Line Bank pursuant to this
Section 1.05(b)(ii)(A) in respect of its Swing Loan Participation in any Swing
Loan, the Swing Line Bank shall be entitled to recover such amount from such
Bank, together with interest thereon for each day from the Participation Payment
Date until the date such amount shall be paid to the Swing Line Bank, at the
Federal Funds Rate until (and including) the third Business Day after the
Participation Payment Date and thereafter at the Base Rate.  Until payment in
full is made by such Bank of all amounts to be paid to the Swing Line Bank by
such Bank in respect of such Swing Loan Participation, the Swing Line Bank shall
hold such Bank's Pro Rata Share of any amount paid by the Borrower after the
Participation Payment Date to the Swing Line Bank in respect of the Swing Loan
to which such Swing Loan Participation relates as security for such Bank's
obligation to make such payment.

          (B) Subject to the final sentence of Section 1.05 (b)(ii)(A), the
Swing Line Bank shall promptly distribute to each Bank its Pro Rata Share of
each payment received (whether directly from the Borrower or otherwise,
including proceeds of any collateral) by the Swing Line Bank after the
Participation Payment Date on account of the principal amount of any Swing 

                                       7

Loan and interest accrued thereon after the Participation Payment Date; provided
                                                                        --------
that in the event that any such payment received by the Swing Line Bank shall be
required to be returned by the Swing Line Bank, for any reason, such Bank shall
return to the Swing Line Bank the portion thereof previously distributed by the
Swing Line Bank to it, but without interest thereon (unless the Swing Line Bank
is required to pay interest on the amount so returned, in which case such Bank
shall be required to pay interest at a like rate). Payments received after the
Participation Payment Date by the Swing Line Bank on account of Swing Loans
shall be applied first to the payment of interest accrued thereon through the
Participation Payment Date.

               (iii)  Obligations of Banks Absolute and Unconditional.
                      ----------------------------------------------- 

          The obligation of each Bank to make an RC Loan to repay Swing Loans as
contemplated by Section 1.05(b)(i) and to purchase Swing Loan Participations in,

contemplated in Section 1.05(b)(ii), shall be absolute, unconditional and
irrevocable.

                ----------------------------------------------------------
Letters of Credit.
- ----------------- 

          Upon the issuance of a Letter of Credit, the Issuing Bank shall be
deemed to have granted to each Participating Bank (including the Issuing Bank in
its capacity as a Bank), and each Participating Bank (including the Issuing Bank
in its capacity as a Bank) shall be deemed to have acquired from the Issuing
Bank, without further action by any party hereto, for its own account and risk,
an undivided interest (each such interest an "LC Participation") in the Issuing
                                              ----------------                 
Bank's rights under Section 1.09(b) in respect of Drawings under such Letter of
Credit to the extent of such Participating Bank's Participating Bank Percentage
thereof.  A Bank that is a Participating Bank with respect to a Letter of Credit
shall remain a Participating Bank with respect to that Letter of Credit
notwithstanding its subsequent designation, if any, as a Nonparticipating Bank
with respect to any other Letter of Credit.

          (b) Funding by Participating Banks of LC Participations.
              --------------------------------------------------- 

          (i)   If the Borrower fails to pay to the Issuing Bank in full the
principal amount of, together with interest accrued on, a Drawing in accordance
with the terms of this Agreement, each Participating Bank that has an LC
Participation in such Letter of Credit shall pay to the Issuing Bank, upon
demand (a "Funding Demand"), its Participating Bank Percentage of such unpaid
           --------------                                                    
amount, in Dollars in funds immediately available to the Issuing Bank at the
Administrative Agent's Office, on, if such demand is made not later 3:00 p.m. on
a Business Day, such Business Day, and, if not, the next Business Day, together
with interest on such amount from the date of the relevant Drawing until such
amount is paid in full at, for the first three days, the Federal Funds Rate and,
thereafter, the Base Rate.

          (ii) Until payment in full of all amounts required to be paid by it
pursuant to Section 1.10(b)(i) in respect of its LC Participation is made by the
Participating Bank obligated to make such payments, the Issuing Bank shall hold
such Participating Bank's Participating Bank Percentage of all amounts paid by
the Borrower in respect of the Drawing relating to such unpaid amount, or in
respect of interest thereon, as security for such Participating Bank's
obligation to make such payment.

          (c) Subject to Section 1.10(b)(ii), if, at any time after a Funding
Demand in respect of a Drawing, the Issuing Bank receives any payment on account
of such Drawing (whether directly from the Borrower or otherwise, including
proceeds of any collateral applied thereto), or any payment on account of
interest thereon, the Issuing Bank shall, subject to Section 1.10(b)(ii),
promptly distribute to each Participating Bank with respect to such Drawing its
Participating Bank Percentage thereof; provided that in the event that any such
                                       --------                                
payment received by the Issuing Bank shall be required to be returned by the
Issuing Bank, for any reason other than pursuant to an Adjudicated Letter of
Credit Claim, such Participating Bank shall return to the Issuing Bank the
portion thereof previously distributed by the Issuing Bank to it, but without
interest thereon (unless the Issuing Bank is required to pay interest on the
amount so returned, in which case the Participating Bank shall be required to
pay interest at the same rate).

          (d) (i)  If any Bank Nonparticipation occurs with respect to a Bank,
(A) the Administrative Agent, the Borrower and such Bank agree, if requested by
the Borrower, to 

                                       11
<PAGE>
 
attempt to locate an Eligible Assignee that will accept the assignment of the
Loans, LC Participations, Commitments and other rights and obligations hereunder
of such Bank and (B) if such an Eligible Assignee is located, such Bank agrees
to assign its interest in its Loans, LC Participations, Commitments and other
rights and obligations hereunder to such Eligible Assignee in accordance with
Section 10.10(a), for a purchase price equal to the unpaid principal amount of
such Bank's Loans and funded LC Participations, together with interest thereon
and fees accrued to the date of payment of such purchase price and all other
amounts at such time payable to such Bank under the Loan Documents. If Loans to
be so assigned include Eurodollar Rate Loans, the assignment thereof shall occur
on the last day of the then-current Interest Periods. If no such assignment is
arranged, the Borrower may, if no Default exists, upon ten days' prior notice to
such Bank, terminate such Bank's Commitments and thereupon promptly prepay such
Bank's Loans and all other amounts payable to such Bank hereunder (including,
without limitation, with respect to its LC Participations and Commitments) and
cash collateralize its LC Participations; provided that prepayments of 
                                          --------    
Eurodollar Rate Loans shall(1) be made on the last day of the applicable
Interest Periods or (2) if made on a day other than the last day of the
applicable Interest Periods, be accompanied by the amount, if any, due with
respect thereto under Section 7.04.

          (ii) If, as a result of the existence of a Bank Nonparticipation with
respect to any Bank, availability of the RC Commitments is reduced, such Bank
shall be deemed to have breached its RC Commitment to the extent of such
reduction and, subject to Section 10.13, shall be liable to the Borrower for any
damages resulting from such reduction.

required to be made by Section 1.14(b) shall be reduced by the amount specified
in such notice to the Administrative Agent, provided that such reduction shall

     Section 1.18  Payments by the Borrower.
                   ------------------------ 

          (a)  Time, Place and Manner.
               ---------------------- 
          All payments due to the Administrative Agent under the Borrower Loan
Documents shall be made to the Administrative Agent  at the Administrative
Agent's Office or at such other address as the Administrative Agent may
designate by notice to the Borrower.  All payments due to the Issuing Bank under
the Borrower Loan Documents by the Borrower or any Bank shall be made to the
Issuing Bank at the Issuing Bank's Office or to such other Person or at such
other address as the Issuing Bank may designate by notice to the Borrower or
such Bank, as the case may be.  All payments due to any Bank under the Borrower
Loan Documents shall, in the case of payments by the Borrower on account of
principal of or interest on the Loans (including Swing Loans, so long as the
Bank that is the Swing Line Bank is also the Administrative Agent) or fees be
made to the Administrative Agent at the Administrative Agent's Office and in the
case of all other payments (including payments of principal of, and interest on,
Swing Loans, if the Bank that is the Swing Line Bank is not the Administrative
Agent), be made directly to such Bank at its Domestic Lending Office or such
other address as such Bank may designate. All payments due to any Bank under the
Borrower Loan Documents, whether made to the Administrative Agent or directly to
such Bank, shall be made for the account of, in the case of payments in respect
of Eurodollar Rate Loans, such Bank's Eurodollar Lending Office and, in the case
of all other payments, such Bank's Domestic Lending Office.  A payment, other
than a payment on account of a Drawing, shall not be deemed to have been made on
any day unless such payment is received by the required Person, at the required
place of payment, in Dollars in funds immediately available to the
Administrative Agent at such place, no later than 12:00 noon on such day.  A
payment on account of a Drawing shall not be deemed to have been made on any day
unless such payment is received by the Issuing Bank at the required place of
payment, in Dollars in funds immediately available to the Issuing Bank at such
place, no later than, in the case of  payments by the Borrower, the times
specified in Section 1.09(b)(i) and, in the case of payments by a Bank, the
times specified in Section 1.10(b).

          (b)  No Reductions.
               ------------- 

          All payments due to the Administrative Agent, the Issuing Bank or any
Bank under the Borrower Loan Documents, and all other terms, conditions,
covenants and agreements to be observed and performed by the Borrower
thereunder, all payments due to the Issuing Bank by a Bank and all payments due
to the Swing Line Bank by a Bank, shall be made, observed or performed by the
Borrower or such Bank, as the case may be, without any reduction or deduction
whatsoever, including any reduction or deduction for any set-off, recoupment,
counterclaim (whether sounding in tort, contract or otherwise) or Tax, except in
the case of payments by the Borrower, subject to Section 1.20, for any
withholding or deduction for Taxes required to be withheld or deducted under
Applicable Law; provided that no payment by any Person to another Person shall
                --------                                                      
constitute a waiver or release by the Person making such payment of any right it
may have against the Person receiving such payment.

          (c)  Extension of Payment Dates.
               -------------------------- 

          Whenever any payment to the Administrative Agent, the Issuing Bank,
the Swing Line Bank or any Bank under the Borrower Loan Documents would
otherwise be due (except by reason of acceleration) on a day that is not a
Business Day, or, in the case of payments of the principal of Eurodollar Rate
Loans, a Eurodollar Business Day, such payment shall instead be due on the next
succeeding Business or Eurodollar Business Day, as the case may be, unless, in
the case of a payment of the principal of a Eurodollar Rate Loan, such extension
would cause payment to be due in the next succeeding calendar month, in which
case such due date shall be advanced to the next preceding Eurodollar Business
Day.  If the date 

                                       17
<PAGE>
 
any payment under the Borrower Loan Documents is due is extended (whether by
operation of any Borrower Loan Document, Applicable Law or otherwise), such
payment shall bear interest for such extended time at the rate of interest
applicable hereunder.

     Section 1.19  Distribution of Payments by the Administrative Agent.
                   ---------------------------------------------------- 

          (a)  The Administrative Agent shall promptly distribute to each Bank
its ratable share of each payment received by the Administrative Agent under the
Loan Documents for the account of the Banks by credit to an account of such Bank
at the Administrative Agent's Office or by wire transfer to an account of such
Bank at an office of any other commercial bank located in the United States of
America.

          (b) Unless the Administrative Agent shall have received notice from
the applicable Loan Party prior to the date on which any payment is due to the
Banks under the Loan Documents that such Loan Party will not make such payment
in full, the Administrative Agent may assume that such Loan Party has made such
payment in full to the Administrative Agent on such date and the Administrative
Agent in its sole discretion may, in reliance upon such assumption, cause to be
distributed to each Bank on such due date a corresponding amount with respect to
the amount then due such Bank.  If and to the extent such Loan Party shall not
have so made such payment in full to the Administrative Agent and the
Administrative Agent shall have so distributed to any Bank a corresponding
amount, such Bank shall, on demand, repay to the Administrative Agent the amount
so distributed together with interest thereon, for each day from the date such
amount is distributed to such Bank until the date such Bank repays such amount
to the Administrative Agent, at the Federal Funds Rate until (and including) the
third Business Day after demand is made and thereafter at the Base Rate.

     Section 1.20  Taxes.
                   ----- 

          (a)  Taxes Payable by the Borrower.
               ----------------------------- 

          If under Applicable Law any Tax is required to be withheld or deducted
from, or is otherwise payable by the Borrower in connection with, any payment to
the Administrative Agent, the Issuing Bank, the Swing Line Bank or any Bank
under the Loan Documents, the Borrower (A) shall (1) if so required, withhold or
deduct the amount of such Tax from such payment and, in any case, pay such Tax
to the appropriate taxing authority in accordance with Applicable Law and (2)
indemnify the Administrative Agent, the Issuing Bank, the Swing Line Bank or
such Bank in accordance with the provisions of Section 10.02(a) against its
failure so to do and (B) shall pay to the Administrative Agent, the Issuing
Bank, the Swing Line Bank or such Bank such additional amounts as may be
necessary so that the net amount received by the Administrative Agent, the
Issuing Bank, the Swing Line Bank or such Bank with respect to such payment,
after withholding or deducting all Taxes required to be withheld or deducted, is
equal to the full amount payable under the Loan Documents less any Bank Taxes
required to be withheld or deducted, or otherwise payable by the Borrower.  If
any Tax is withheld or deducted from, or is otherwise payable by the Borrower in
connection with, any payment payable to the Administrative Agent, the Issuing
Bank, the Swing Line Bank or any Bank under the Loan Documents, the Borrower
shall, as soon as possible after the date of such payment, furnish to the
Administrative Agent, the Issuing Bank, the Swing Line Bank or such Bank the
original or a certified copy of a receipt for such Tax from the applicable
taxing authority.  If any payment due to the Administrative Agent, the Issuing
Bank, the Swing Line Bank or any Bank under the Loan Documents is or is expected
to be made without withholding or deducting therefrom, or otherwise paying in
connection therewith, any Tax payable to any taxing authority, the Borrower

                                       18
<PAGE>
 
shall, within 30 days after any request from the Administrative Agent, furnish
to the Administrative Agent a certificate from such taxing authority, or an
opinion of counsel acceptable to the Administrative Agent, in either case
stating that no Tax payable to such taxing authority was or is, as the case may
be, required to be withheld or deducted from, or otherwise paid by the Borrower
in connection with, such payment.

          (b) Taxes Payable by the Administrative Agent, the Issuing Bank or any
              ------------------------------------------------------------------
Bank.
- ---- 

          The Borrower shall, promptly upon request by the Administrative Agent,
the Issuing Bank, the Swing Line Bank or any Bank for the payment thereof, pay
to the Administrative Agent, the Issuing Bank, the Swing Line Bank or such Bank
(A) all Taxes (other than Bank Taxes) payable by the Administrative Agent, the
Issuing Bank or such Bank with respect to any payment due to the Administrative
Agent, the Issuing Bank, the Swing Line Bank or such Bank under the Loan
Documents and (B) all Taxes payable by the Administrative Agent, the Issuing
Bank, the Swing Line Bank or such Bank as a result of payments made by the
Borrower (whether made to a taxing authority or to the Administrative Agent, the
Issuing Bank or such Bank) pursuant to this Section 1.20(b).

          (c) Exemption from U.S. Withholding Taxes.
              ------------------------------------- 

          There shall be submitted to the Borrower and the Administrative Agent
(A) on or before the first date that interest or fees are payable to such Bank

each of the Issuing Bank and the Swing Line Bank if it is not, and by each Bank
that is not, a United States Person, two duly completed and signed copies of
Internal Revenue Service Form 1001 or 4224, in either case entitling such Person

a Non-US Bank or (2) if at the time any of the foregoing are inapplicable, duly
completed and signed copies of such form, if any, as entitles such Person to
exemption from withholding of United States federal income taxes to the maximum
extent to which such Person is then entitled under Applicable Law and (B) from
time to time thereafter, prior to the expiration or obsolescence of any
previously delivered form or upon any previously delivered form becoming
inaccurate or inapplicable, such further duly completed and signed copies of
such form, if any, as entitles such Person to exemption from withholding of
United States federal income taxes to the maximum extent to which such Person is
then entitled under Applicable Law.  Each such Person shall promptly notify the
Borrower and the Administrative Agent if (A) it is required to withdraw or
cancel any form or certificate previously submitted by it or any such form or
certificate has otherwise become ineffective or inaccurate or (B) payments to it
are or will be subject to withholding of United States federal income taxes to a
greater extent than the extent to which payments to it were previously subject.
Upon the request of the Borrower or the Administrative Agent, each such Person
that is a United States Person shall from time to time submit to the Borrower
and the Administrative Agent a certificate to the effect that it is such a
United States Person and a duly completed Internal Revenue Service Form W-9 (and
from time to time thereafter, any appropriate form that identifies such Person
as a United States Person, as required under Applicable Law).

Regulatory Change Enacted after the Agreement Date and (2) in the case of a

after such Person becomes a Bank or (C) to the extent such withholding is

Bank that is a Non-US Bank, to cause its Notes to be issued as Registered Notes.

the following conditions:

          (a) such Bank shall have received a notice of or request for a

basis of which, the interest rate applicable to Eurodollar Rate Loans of that
Type is directly or indirectly determined or (ii) the category of assets that
includes Eurodollar Rate Loans of that Type.

     If, as a result of this Section 7.01, any Loan of any Bank that would
otherwise be made or maintained as or converted into a Eurodollar Rate Loan of
any Type for any Interest Period is instead made or maintained as or converted
into a Base Rate Loan, then, unless the corresponding Loan of each of the other
Banks is also to be made or maintained as or converted into a Base Rate Loan,
such Loan shall be treated as being a Eurodollar Rate Loan of such Type for such
Interest Period for all purposes of this Agreement (including the timing,
application and proration among the Banks of interest payments, conversions and
prepayments) except for the calculation of the interest rate borne by such Loan.
The Administrative Agent shall promptly notify the Borrower and each Bank of the
existence or occurrence of any condition or circumstance specified in clause (a)
above, and each Bank shall promptly notify the Borrower and the Administrative
Agent of the existence or occurrence of any condition or circumstance specified
in clause (b), (c) or (d) above applicable to such Bank's Loans, but the failure
by the Administrative Agent or such Bank to give any such notice shall not
affect such Bank's rights hereunder.

     Section 7.02  Regulatory Changes.
                   ------------------ 

     If (a) any Regulatory Change shall directly or indirectly (i)(A) in the
determination of any Bank, reduce the amount of any sum received or receivable
by such Bank with respect to any Loan, LC Participation or Swing Loan
Participation or the return to be earned by such Bank on any Loan, LC
Participation or Swing Loan Participation or (B) in the determination of the
Issuing Bank, reduce the amount of any sum received or receivable by the Issuing
Bank with respect to any Letter of Credit, Drawing or 

                                       41
<PAGE>
 
Contingent Reimbursement Obligation, or the return to be earned by the Issuing
Bank on any Letter of Credit, Drawing or Contingent Reimbursement Obligation,
(ii)(A) in the determination of any Bank, impose a cost on such Bank or any
Affiliate of such Bank that is attributable to the making or maintaining of, or
such Bank's commitment to make or acquire, any Loan or LC Participation or to
purchase any Swing Loan Participation, or (B) in the determination of the
Issuing Bank, impose a cost on the Issuing Bank or any of its Affiliates that is
attributable to the issuance or maintenance of, or the commitment to issue, any
Letter of Credit or the making or maintaining of any Drawing or Contingent
Reimbursement Obligation, (iii)(A) in the determination of any Bank, require
such Bank or any Affiliate to make any payment on or calculated by reference to
the gross amount of any amount received by such Bank under any Loan Document or
(B) in the determination of the Issuing Bank, require the Issuing Bank or any of
its Affiliates to make any payment on or calculated by reference to the gross
amount of any amount received by the Issuing Bank or any of its Affiliates in
respect of (1) any Letter of Credit or its commitment to issue any Letter of
Credit or (2) any Drawing or Contingent Reimbursement Obligation or (iv)(A) in
the determination of any Bank, reduce, or have the effect of reducing, the rate
of return on the capital of such Bank or any Affiliate of such Bank allocable to
any Loan, LC Participation, Swing Loan Participation or such Bank's commitment
to make any Loan, acquire any LC Participation or purchase any Swing Loan
Participation or (B) in the determination of the Issuing Bank, reduce, or have
the effect of reducing, the rate of return on the capital of the Issuing Bank or
any of its Affiliates allocable to (1) any Letter of Credit or its commitment to
issue any Letter of Credit or (2) any Drawing or Contingent Reimbursement
Obligation and (b) such reduction, increased cost or payment shall not be fully
compensated for by an adjustment in the applicable rates of interest payable
under the Loan Documents, then the Borrower shall pay to such Bank or the
Issuing Bank, as the case may be, such additional amounts as such Bank or the
Issuing Bank, as the case may be, determines will, together with any adjustment
in the applicable rates of interest payable hereunder, fully compensate for such
reduction, increased cost or payment. Such additional amounts shall be payable,
in the case of those applicable to prior periods, within 15 days after request
by such Bank or the Issuing Bank, as the case may be, for such payment and, in
the case of those applicable to future periods, on the dates specified, or
determined in accordance with a method specified, by such Bank or the Issuing
Bank, as the case may be. Each Bank and the Issuing Bank will promptly notify
the Borrower of any determination made by such Bank or the Issuing Bank, as the
case may be, referred to in clauses (a) and (b) above, but the failure to give
such notice shall not affect the right of such Bank or the Issuing Bank, as the
case may be, to compensation.

     Section 7.03  Capital Requirements.
                   -------------------- 

     If, (a) in the determination of any Bank, such Bank or any of its
Affiliates is required to maintain capital on account of any Loan, LC
Participation or Swing Loan Participation or such Bank's commitment to make any
Loan, acquire any LC Participation or purchase any Swing Loan Participation in a
greater amount than such Bank or such Affiliate would otherwise have been so
required to maintain on account thereof, or (b) in the determination of the
Issuing Bank, the Issuing Bank or any of its Affiliates is required to maintain
capital on account of (i) any Letter of Credit or its commitment to issue any
Letter of Credit or (ii) any Drawing or Contingent Reimbursement Obligation in a
greater amount than the Issuing Bank or such Affiliate otherwise would have been
so required to maintain on account thereof, then, upon request by such Bank or
the Issuing Bank, as the case may be, the Borrower shall from time to time
thereafter pay to such Bank or the Issuing Bank, as the case may be, such

                                       42
<PAGE>
 
additional amounts as such Bank or the Issuing Bank, as the case may be,
determines will fully compensate it for any reduction in the rate of return on
the additional capital that such Bank, or the Issuing Bank, or such Affiliate of
either thereof, as the case may be, is so required to maintain.  Such additional
amounts shall be payable, in the case of those applicable to prior periods,
within 15 days after request by such Bank or the Issuing Bank, as the case may
be, for such payment and, in the case of those relating to future periods, on
the dates specified, or determined in accordance with a method specified, by
such Bank or the Issuing Bank, as the case may be.

     Section 7.04  Funding Losses.
                   -------------- 

     The Borrower shall pay to each Bank, upon request, such amount or amounts
as such Bank determines are necessary to compensate it for any loss, cost or
expense incurred by it as a result of (a) in the case of Eurodollar Rate Loans,
(i) any payment  (including a payment pursuant to Section 1.14(c)), prepayment
or conversion of a Eurodollar Rate Loan on a date other than the last day of an
Interest Period for such Eurodollar Rate Loan or (ii) a Eurodollar Rate Loan for
any reason not being made or converted, or any payment of principal thereof or
interest thereon not being made, on the date therefor determined in accordance
with the applicable provisions of this Agreement, and (b) in the case of Agreed
Rate Loans, (i) any payment or prepayment of an Agreed Rate Loan on a date other
than the last day of an Agreed Rate Interest Period or (ii) an Agreed Rate Loan
for any reason not being made, or any payment of principal thereof or interest
thereon not being made, on the date required therefor determined in accordance
with the applicable provisions of this Agreement, including any loss incurred in
obtaining, liquidating or employing deposits from third parties, but excluding
loss of margin for the period after any such payment or conversion or failure to
borrow, convert, continue or prepay.

     Section 7.05  Certain Determinations.
                   ---------------------- 

     In making the determinations contemplated by Sections 7.01, 7.02, 7.03 and
7.04, each Bank may make such estimates, assumptions, allocations and the like
that such Bank in good faith reasonably determines to be appropriate, and each
Bank's selection thereof in accordance with this Section 7.05, and the
determinations made by such Bank on the basis thereof, shall be final, binding
and conclusive upon the Borrower, except, for manifest errors.  Each Bank shall
furnish to the Borrower upon request a certificate outlining in reasonable
detail the computation of any amounts claimed by it under Sections 7.02, 7.03
and 7.04 and the assumptions underlying such computations.

     Section 7.06  Change of Lending Office.
                   ------------------------ 

     If an event occurs with respect to a Lending Office that obligates the
Borrower to pay any amount under Section 1.20, makes operable the provisions of
clause (b) or (c) of Section 7.01 or entitles any Bank to make a claim under
Section 1.20(a), 7.02 or 7.03, such Bank shall, if requested by the Borrower,
use reasonable efforts to designate another Lending Office or Offices the
designation of which will reduce the amount the Borrower is so obligated to pay,
eliminate such operability or reduce the amount such Bank is so entitled to
claim, provided that such designation would not, in the sole and absolute
discretion of such Bank, be disadvantageous to such Bank in any manner or
contrary to Bank policy.  Each Bank may at any time and from time to time change
any Lending Office and shall give notice of any such change to the Borrower.
Except in the case of a change in Lending Offices made at the request of the
Borrower, the designation of a new Lending Office by any Bank shall not obligate
the Borrower to pay any amount to such Bank under Section 1.20, make operable
the provisions of clause (b) or (c) of Section 7.01 or entitle the Bank to make
a claim under Section 1.20(a), 

                                       43
<PAGE>
 
7.02 or 7.03 if such obligation, the operability of such clause or such claim
results solely from such designation and not from a Regulatory Change Enacted
thereafter.

                            THE ADMINISTRATIVE AGENT
                            ------------------------

     Section 8.01  Appointment and Powers.
                   ---------------------- 

     Each Bank, the Swing Line Bank and the Issuing Bank hereby irrevocably
appoints and authorizes the Administrative Agent, and the Administrative Agent
hereby agrees, to act as the agent for and representative (within the meaning of
Section 9-105(m) of the Uniform Commercial Code) of such Bank and the Issuing
Bank under the Loan Documents with such powers as are delegated to the
Administrative Agent and the Secured Party by the terms thereof, together with
such other powers as are reasonably incidental thereto.  The Administrative
Agent's duties shall be purely ministerial and it shall have no duties or
responsibilities except those expressly set forth in the Loan Documents.  The
Administrative Agent shall not be required under any circumstances to take any
action that, in its judgment, (a) is contrary to any provision of the Loan
Documents or Applicable Law or (b) would expose it to any Liability or expense
against which it has not been indemnified to its satisfaction.  The
Administrative Agent shall not, by reason of its serving as the Administrative
Agent, be a trustee or other fiduciary for any Bank or the Issuing Bank.

     Section 8.02  Limitation on Administrative Agent's Liability.
                   ---------------------------------------------- 

     Neither the Administrative Agent nor any of its directors, officers,
employees or agents shall be liable or responsible for any action taken or
omitted to be taken by it or them under or in connection with the Loan
Documents, except for its or their own gross negligence, willful misconduct or
knowing violations of law.  The Administrative Agent shall not be responsible to
any Bank or the Issuing Bank for (a) any recitals, statements, representations
or warranties contained in the Loan Documents or in any certificate or other
document referred to or provided for in, or received by any of the Banks under,
the Loan Documents, (b) the validity, effectiveness or enforceability of the
Loan Documents or any such certificate or other document, (c) the value or
sufficiency of the Collateral, or (d) any failure by the Loan Parties to perform
any of their obligations under the Loan Documents.  The Administrative Agent may
employ agents and attorneys-in-fact and shall not be responsible for the
negligence or misconduct of any such agents or attorneys-in-fact so long as the
Administrative Agent was not grossly negligent in selecting or directing such
agents or attorneys-in-fact.  The Administrative Agent shall be entitled to rely
upon any certification, notice or other communication (including any thereof by
telephone, telex, telecopier, telegram or cable) believed by it to be genuine
and correct and to have been signed or given by or on behalf of the proper
Person or Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Administrative Agent.  As to any
matters not expressly provided for by the Loan Documents, the Administrative
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under the Loan Documents in accordance with instructions signed by the
Required Banks, and such instructions of the Required Banks and any action taken
or failure to act pursuant thereto shall be binding on all of the Banks.

     Section 8.03  Defaults.
                   -------- 

     The Administrative Agent shall not be deemed to have knowledge of the
occurrence of a Default (other than the non-payment to it of principal of or
interest on Loans or fees) unless the Administrative Agent has received notice
from a Bank, or 

                                       44
<PAGE>
 
the Borrower specifying such Default and stating that such notice is a "Notice
of Default". In the event that the Administrative Agent has knowledge of such a
non-payment or receives such a notice of the occurrence of a Default, the
Administrative Agent shall give prompt notice thereof to the Banks and the
Issuing Bank. In the event of any Default, the Administrative Agent shall (a) in
the case of a Default that constitutes an Event of Default, take any or all of
the actions referred to in clauses (a), (b) and (c) of the first sentence of
Section 6.02 if so directed by the Required Banks and (b) in the case of any
Default, take such other action with respect to such Default as shall be
reasonably directed by the Required Banks. Unless and until the Administrative
Agent shall have received such directions, in the event of any Default, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default as it shall deem
advisable in the best interests of the Banks and the Issuing Bank.

     Section 8.04  Rights as a Bank.
                   ---------------- 

     Each Person acting as the Administrative Agent that is also a Bank shall,
in its capacity as a Bank, have the same rights and powers under the Loan
Documents as any other Bank and may exercise the same as though it were not
acting as the Administrative Agent, and the term "Bank" or "Banks" shall include
such Person in its individual capacity.  Each Person acting as the
Administrative Agent (whether or not such Person is a Bank) and its Affiliates
may (without having to account therefor to any Bank) accept deposits from, lend
money to and generally engage in any kind of banking, trust or other business
with the Loan Parties and their Affiliates as if it were not acting as the
Administrative Agent, and such Person and its Affiliates may accept fees and
other consideration from the Loan Parties and their Affiliates for services in
connection with the Loan Documents or otherwise without having to account for
the same to the Banks.

     Section 8.05  Indemnification.
                   --------------- 

     The Banks agree to indemnify the Administrative Agent (to the extent not
reimbursed by the Loan Parties under the Loan Documents), ratably on the basis
of the respective aggregate principal amounts of the Exposures of the Banks and
the Term A Loans and Term B Loans outstanding made by the Banks (or, if no
Exposures, Term A Loans or Term B Loans are at the time outstanding, ratably on
the basis of their respective Commitments), for any and all Liabilities, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Administrative Agent (including the costs and expenses that
the Loan Parties are obligated to pay under the Loan Documents) in any way
relating to or arising out of the Loan Documents or any other documents
contemplated thereby or referred to therein or the transactions contemplated
thereby or the enforcement of any of the terms thereof or of any such other
documents, provided that no Bank shall be liable for any of the foregoing to the
extent (a) they are subject to the indemnity contemplated by the last sentence
of Section 10.10(b) or (b) they arise from gross negligence, willful misconduct
or knowing violations of law by the Administrative Agent.

     Section 8.06  Non-Reliance on Administrative Agent and Other Banks.
                   ---------------------------------------------------- 

     Each Bank and the Issuing Bank agrees that it has made and will continue to
make, independently and without reliance on the Administrative Agent or any
other Bank, and based on such documents and information as it deems appropriate,
its own credit analysis of the Loan Parties, its own evaluation of the
Collateral and its own decision to enter into the Loan Documents and to take or
refrain from taking any action in connection therewith.  The Administrative
Agent shall not be 

                                       45
<PAGE>
 
required to keep itself informed as to the performance or observance by the Loan
Parties of the Loan Documents or any other document referred to or provided for
therein or to inspect the properties or books of any Loan Party or any
Subsidiary thereof or the Collateral. Except for notices, reports and other
documents and information expressly required to be furnished to the Banks and
the Issuing Bank by the Administrative Agent under the Loan Documents, the
Administrative Agent shall have no obligation to provide any Bank or the Issuing
Bank with any information concerning the business, status or condition of any
Loan Party or any Subsidiary thereof or the Loan Documents or the Collateral
that may come into the possession of the Administrative Agent or any of its
Affiliates.

     Section 8.07  Execution and Amendment of Loan Documents on Behalf of the
                   ----------------------------------------------------------
Banks.
- ----- 

Each Bank hereby authorizes the Administrative Agent to execute and deliver, in
the name of and on behalf of such Bank, (a) any Pledge Agreement, (b) all UCC
financing and continuation statements and other documents the filing or
recordation of which are, in the determination of the Administrative Agent,
necessary or appropriate to create, perfect or maintain the existence or
perfected status of the Security Interest and (c) any other Loan Document
requiring execution by or on behalf of such Bank other than, in the case of the
Issuing Bank, Letters of Credit and Applications.  The Administrative Agent
shall consent to any amendment of any term, covenant, agreement or condition of
the Pledge Agreement, or to any waiver of any right thereunder, if, but only if,
the Administrative Agent is directed to do so in writing by the Required Banks;
                                                                               
provided that (a) the Administrative Agent shall not be required to consent to
- --------                                                                      
any such amendment or waiver that affects its rights or duties and (b) the
Administrative Agent shall not, unless directed to do so in writing by each
Bank, (i) consent to any assignment by any Loan Party of any of its rights or
obligations under any such agreement or (ii) release any Collateral from the
Security Interest, except as required or contemplated by the Loan Documents.

     Section 8.08  Resignation of the Administrative Agent.
                   --------------------------------------- 

     The Administrative Agent may at any time give notice of its resignation to
the Banks, the Issuing Bank and the Borrower.  Upon receipt of any such notice
of resignation, the Required Banks and the Issuing Bank may, after consultation
with the Borrower, appoint a successor Administrative Agent.  If no successor
Administrative Agent shall have been so appointed by the Required Banks and the
Issuing Bank and shall have accepted such appointment within 30 days after the
retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of the Banks and the Issuing Bank
and after consultation with the Borrower, appoint a successor Administrative
Agent.  Upon the acceptance by any Person of its appointment as a successor
Administrative Agent, such Person shall thereupon succeed to and become vested
with all the rights, powers, privileges, duties and obligations of the retiring
Administrative Agent and the retiring Administrative Agent shall be discharged
from its duties and obligations as Administrative Agent under the Loan Documents
and (b) the retiring Administrative Agent shall promptly transfer all Collateral
within its possession or control to the possession or control of the successor
Administrative Agent and shall execute and deliver such notices, instructions
and assignments as may be necessary or desirable to transfer the rights of the
Administrative Agent with respect to the Collateral to the successor
Administrative Agent.  After any retiring Administrative Agent's resignation as
Administrative Agent, the provisions of this Article 8 shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as the Administrative Agent.

     Section 9.01  Guaranty of Payment.
                   ------------------- 

     The Borrower and each of the Guarantors hereby (a) guarantees to each Bank,
the Issuing Bank, the Swing Line Bank and each holder of a Note the due and
punctual payment of all of the Guaranteed Obligations (other than those that
constitute Liabilities of such Guarantor) in accordance with their respective
terms and when and as due (whether at maturity, by reason of acceleration or
otherwise), or deemed to be due pursuant to Section 9.03, and (b) agrees so to
pay the same when so due, or deemed to be due, upon demand.

     Section 9.02  Limitation on Guaranty.
                   ---------------------- 

     It is the intention of the Borrower, each of the Guarantors, the Banks, the
Issuing Bank and the Swing Line Bank that the obligations of the Borrower and
each such Guarantor under Section 9.01 shall be in, but not in excess of, the
maximum amount permitted by Applicable Law.  To that end, but only to the extent
such obligations would otherwise be void, voidable or otherwise unenforceable,
the obligations of the Borrower and each such Guarantor hereunder shall be
limited to the maximum amount that would not make such obligations void,
voidable or otherwise unenforceable.  This Section 9.02 is intended solely to
preserve the rights of each Bank, the Issuing Bank, the Swing Line Bank and each
holder of a Note hereunder to the maximum extent permitted by Applicable Law,
and neither the Borrower, any Guarantor nor any other Person shall have any
right under this Section 9.02 that it would not otherwise have under Applicable
Law.

     Section 9.03  Continuance and Acceleration of Guaranteed Obligations upon
                   -----------------------------------------------------------
Certain Events.
- -------------- 

     If:

          (a) any Event of Default that this Agreement states is to result in
     the automatic acceleration of any Guaranteed Obligations shall occur;

          (b) any injunction, stay or the like that enjoins any acceleration, or
     demand for the payment of any Guaranteed Obligations that would otherwise
     be required or permitted hereunder shall become effective; or

          (c) any Guaranteed Obligations shall be or be determined to be or
     become discharged, disallowed, invalid, illegal, void or otherwise
     unenforceable (whether by operation of any present or future law or by
     order of any court or governmental agency) against the Borrower;

then (i) such Guaranteed Obligations shall, for all purposes hereof, be deemed
(A) in the case of clause (c), to continue to be outstanding and in full force
and effect notwithstanding the unenforceability thereof against the Borrower and
(B) if such is not already the case, to have thereupon become immediately due
and payable and, if subject thereto, to have commenced bearing interest at the
Post-Default Rate and (ii) such Bank, the Issuing Bank, the Swing Line Bank or
other holder of a Note to which such Guaranteed Obligations are owing may, with
respect to such Guaranteed Obligations, exercise all of the rights and remedies
under the Borrower Loan Documents that would be available to them during an
Event of Default.

     Section 9.04  Recovered Payments.
                   ------------------ 

     The Guaranteed Obligations shall be deemed not to have been paid, and the
Borrower's and each Guarantor's obligations hereunder in respect thereof shall
continue and not be discharged, to the extent that any payment thereof by the
Borrower or any other guarantor, or out of the proceeds of any collateral, is
recovered from or paid over by or for the account of any Bank, the Issuing Bank,
the Swing Line Bank or other holder of a Note for any reason, including as a
preference or fraudulent transfer or by virtue of any subordination (whether
present or future or contractual or otherwise) of the Guaranteed Obligations,
whether such recovery or payment over is effected by any judgment, decree or
order of any court or governmental agency, by any plan of reorganization or by
settlement or compromise by such Bank, the Issuing Bank, the Swing Line Bank or
other holder of a Note (whether or not consented to by the Borrower, any
Guarantor or any other guarantor) of any claim for any such recovery or payment
over.  The Borrower and each Guarantor hereby expressly waives the benefit of
any applicable statute of limitations and agrees that it shall be liable
hereunder with respect to any Guaranteed Obligation whenever such a recovery or
payment over thereof occurs.

     Section 9.05  Evidence of Guaranteed Obligations.
                   ---------------------------------- 

     The records of the Administrative Agent, the Issuing Bank, the Swing Line
Bank and each Bank and other holder of a Note shall be conclusive evidence of
the Guaranteed Obligations owing to it and of all payments in respect thereof.

     Section 9.06  Binding Nature of Certain Adjudications.
                   --------------------------------------- 

     The Borrower and each Guarantor shall be conclusively bound by the
adjudication in any action or proceeding, legal or otherwise, involving any
controversy arising under, in connection with, or in any way related to, any of
the Guaranteed Obligations, and by a judgment, award or decree entered therein.

     Section 9.07  Nature of Guarantor's Obligations.
                   --------------------------------- 

     The Borrower's and each Guarantor's obligations hereunder (a) are absolute
and unconditional, (b) are unlimited in amount except as provided in Section
9.02, (c) constitute a guaranty of payment and not a guaranty of collection, (d)
are as primary obligor and not as a surety only, (e) shall be a continuing
guaranty of all present and future Guaranteed Obligations and all promissory
notes and other documentation given in extension or renewal or substitution for
any of the Guaranteed Obligations and (f) shall be irrevocable.

     Section 9.08  No Release of Guarantor.
                   ----------------------- 

     THE OBLIGATIONS OF THE BORROWER AND EACH GUARANTOR UNDER THIS ARTICLE 9
SHALL NOT BE REDUCED, LIMITED OR TERMINATED, NOR SHALL THE BORROWER OR SUCH
GUARANTOR BE DISCHARGED FROM ANY THEREOF, FOR ANY REASON WHATSOEVER (other than,
subject to Section 9.04, the payment of the Guaranteed Obligations), INCLUDING
(and whether or not the same shall have occurred or failed to occur once or more
than once and whether or not the Borrower or such Guarantor shall have received
notice thereof) ANY ACT OR FAILURE TO ACT OR ANY OTHER EVENT OR CIRCUMSTANCE
THAT (i) VARIES THE RISK OF THE BORROWER OR SUCH GUARANTOR HEREUNDER OR (ii) BUT
FOR THE PROVISIONS HEREOF, WOULD, AS A MATTER OF STATUTE OR RULE OF LAW OR
EQUITY, OPERATE TO REDUCE, LIMIT OR TERMINATE THE OBLIGATIONS OF THE BORROWER OR

                    ------------------- 

     Any term, covenant, agreement or condition of the Loan Documents may be
amended, and any right under the Loan Documents may be waived, if, but only if,

amendment or waiver with respect to the documents referred to in Section 8.07,

Administrative Agent, (b) in the case of an amendment or waiver with respect
to any Loan Document, the Required Banks and, if the rights and duties of the
Administrative Agent, the Issuing Bank or the Swing Line Bank are affected
thereby, by the Administrative Agent, the Issuing Bank or the Swing Line Bank,
as the case may be, and (c) in the case of an amendment, by the Borrower;
provided that no amendment or waiver shall be effective, unless in writing and
- --------                                                                      
signed by each Bank affected thereby, to the extent it (A) increases the amount
of such Bank's Commitments, (B) reduces the principal of or the rate of interest
on such Bank's Loans or Notes or any of the Drawings or the fees payable to such
Bank hereunder, (C) postpones any date fixed for (1) any payment of principal of
or interest on such Bank's Loans or Notes, any of the Drawings or the fees
payable to such Bank hereunder or (2) the expiration of any Letter of Credit if
such postponement would extend the expiration date of such Letter of Credit
beyond the RC Termination Date, (D) releases any Guarantor from its Guaranty of
the Guaranteed Obligations, (E) release any Collateral from the Security
Interest, unless such release is specifically provided for or contemplated in
the Loan Documents, (F) amends Section 1.21, this Section 10.07, the final
sentence of Section 1.02(a)(ii), the definition of "Required Banks" or any other
provision of this Agreement requiring the consent or other action of all of the

           --------  -------                                            
permitted to be amended or waived by Required Banks, which amendment or waiver
would have an effect on the rights or interests of any Lender Group under the
Loan Documents that is (x) adverse to such Lender Group and (y) disproportionate
in such effect to the effect that such amendment or waiver would have on the
rights or interests of any other Lender Group under the Loan Documents, shall be
effective, unless in writing and signed by Banks comprising 51% or more of such
first Lender Group, based on the Commitments or, if such Commitments shall have
expired or been terminated, based on the Term A Loans or Term B Loans, as the
case may be, outstanding (in the case of the Term A Banks or the Term B Banks)
or the Exposures outstanding (in the case of the RC Banks), of such Lender
Group.  Unless otherwise specified in such waiver, a waiver of any right under
the Loan Documents shall be effective only in the specific instance and for the
specific purpose for which given.  No election not to exercise, failure to
exercise or delay in exercising any right, nor any course of dealing or
performance, shall operate as a waiver of any right of the Administrative Agent,
the Issuing Bank, the Swing Line Bank or any Bank under the Loan Documents or
Applicable Law, nor shall any single or partial exercise of any such right
preclude any other or further exercise thereof or the exercise of any other
right of such Person under the Loan Documents or Applicable Law.

     Section 10.08  Set-Off; Suspension of Payment and Performance.
                    ---------------------------------------------- 

     The Administrative Agent, the Issuing Bank, the Swing Line Bank and each
Bank is hereby authorized by the Borrower and each Guarantor, at any time and
from time to time, without notice, (a) during any Event of Default, to set off
against, and to appropriate and apply to the payment of, the Liabilities of such
Person under the Loan Documents (whether owing to the Administrative Agent, the
Issuing Bank, the Swing Line Bank or such Bank or to any other Person that is
the Administrative Agent, the Issuing Bank, the Swing Line Bank or a Bank and
whether matured or unmatured, fixed or contingent or liquidated or unliquidated)
any and all Liabilities owing by the Administrative Agent, the Issuing Bank, the
Swing Line Bank or such Bank or any of its Affiliates to such Person (whether
payable in Dollars or any other currency, whether matured or unmatured and, in
the case of Liabilities that are deposits, whether general or special, time or
demand and however evidenced and whether maintained at a branch or office
located within or without the United States of America) and (b) during any
Default, to suspend the payment and 

                                       54
<PAGE>
 
performance of such Liabilities owing by such Person or its Affiliates in an
amount of the Loans and Drawings plus interest accrued thereon and other amounts
then due and payable under the Loan Documents and, in the case of Liabilities
that are deposits, to the extent necessary, to return as unpaid for insufficient
funds any and all checks and other items drawn against such deposits.

     Section 10.09  Sharing of Recoveries.
                    --------------------- 

          (a)  Each Bank agrees that, if, for any reason, including as a result
of (i) the exercise of any right  of counterclaim, set-off, banker's lien or
similar right, (ii) its claim in any applicable bankruptcy, insolvency or other
similar law being deemed secured by a Debt owed by it to any Loan Party,
including a claim deemed secured under Section 506 of the Bankruptcy Code or
(iii) the allocation of payments by the Administrative Agent or any Loan Party
in a manner contrary to the provisions of Section 1.21, such Bank shall receive
payment of a proportion of the aggregate amount due and payable to it hereunder
(A) as principal of or interest on the Loans or with respect to any LC
Participation or any Swing Loan Participation or (B) fees that is greater than
the proportion received by any other Bank in respect of the respective
aggregates of such amounts due and payable to such other Bank hereunder, then
the Bank receiving such proportionately greater payment shall purchase
participations (which it shall be deemed to have done simultaneously upon the
receipt of such payment) in the rights of the other Banks hereunder in such
Loans or fees, as the case may be, so that all such recoveries with respect to
such respective amounts due and payable hereunder (net of costs of collection)
shall be pro rata; provided that if all or part of such proportionately greater
                   --------                                                    
payment received by the purchasing Bank is thereafter recovered by or on behalf
of any Loan Party from such Bank, such purchases shall be rescinded and the
purchase prices paid for such participations shall be returned to such Bank to
the extent of such recovery, but without interest (unless the purchasing Bank is
required to pay interest on the amount recovered to the Person recovering such
amount, in which case the selling Bank shall be required to pay interest at a
like rate).  The Borrower expressly consents to the foregoing arrangements and
agrees that any holder of a participation in any rights hereunder so purchased
or acquired pursuant to this Section 10.09(a) shall, with respect to such
participation, be entitled to all of the rights of a Bank as fully as though it
were a Bank under Sections 1.20, 7.02 through 7.06, 10.02 and 10.08 (subject to
any condition imposed on a Bank hereunder with respect thereto) and may exercise
any and all rights of set-off with respect to such participation as fully as
though the Borrower were directly indebted to the holder of such participation
for Loans in the amount of such participation.

          (b) Each Bank agrees to exercise any right of counterclaim, set-off,
banker's lien or similar right that it may have in respect of any Loan Party in
a manner so as to apportion the amount subject to such exercise, on a pro rata
basis, first, between (i) obligations of such Loan Party for amounts subject to
the sharing provisions of Section 10.09(a) and (ii) other Liabilities of such
Loan Party and, second, with respect to amounts allocated to obligations of such
Loan Party referred to in clause (i), between, first, to Loans and second, Swing
Loan Participations.

     Section 10.10  Assignments and Participations.
                    ------------------------------ 

          (a)  Assignments.
               ----------- 

          (i)  Neither the Borrower nor any other Loan Party may assign any of
its rights or obligations under the Loan Documents to which it is a party
without the prior written consent of (A) in the case of the documents referred
to in Section 8.07, the Administrative Agent and (B) in the case of any of the
other Loan Documents, each Bank, and no assignment of any such obligation shall
release the Borrower or such other Loan Party therefrom unless the
Administrative Agent or each Bank, as 

                                       55
<PAGE>
 
applicable, shall have consented to such release in a writing specifically
referring to the obligation from which the Borrower or such other Loan Party is
to be released.

          (ii) Each Bank may from time to time assign any or all of its rights
and obligations under any Loan Documents to one or more Persons; provided that,
                                                                 --------      
except in the case of the grant of a security interest to a Federal Reserve Bank
(which may be made without condition or restriction), no such assignment shall
be effective unless (A) the assignment is consented to by the Administrative
Agent, the Issuing Bank, the Swing Line Bank and the Borrower (which consent
shall not be unreasonably withheld or delayed), and provided, further,  that the
                                                    --------  -------           
consent of the Borrower shall not be required (x) in the case of any assignment

          (b)  Participation.
               ------------- 

          Each Bank may from time to time sell or otherwise grant participations
in any or all of its rights and obligations under the Borrower Loan Documents
without the consent of the Borrower, any Guarantor, the Issuing Bank, the Swing
Line Bank or any other Bank; provided that no such grant of a participation
                             --------                                      
shall be effective unless consented to by the Administrative Agent (which
consent shall not be unreasonably withheld or delayed).  In the event of any
such grant by a Bank of a participation, such Bank's obligations under the Loan
Documents to the other parties thereto shall remain unchanged, such Bank shall
remain solely responsible for the performance thereof, and the Borrower, the
Guarantors, the Administrative Agent, the Issuing Bank, the Swing Line Bank and
the other Banks may continue to deal solely and directly with such Bank in
connection with such Bank's rights and obligations thereunder.  A Bank may not
grant to any holder of a participation the right to require such Bank to take or
omit to take any action under the Loan Documents, except that a Bank may grant
to any such holder the right to require such holder's consent to  (i) reduce the
principal of or the rate of interest on such Bank's Loans or any of the Drawings
or the fees payable to such Bank hereunder,  (ii) postpone any date fixed for
(A) any payment of principal of or interest on such Bank's Loans, any of the
Drawings or the fees payable to such Bank hereunder or (B) the expiration of any
Letter of Credit if such postponement would extend the expiration date of such

Letter of Credit beyond the RC Termination Date,  (iii)  permit any Loan Party
to assign any of its obligations under the Loan Documents to any other Person,
(iv)  release any Guarantor from its obligations under Article 9 or (v) release
any Collateral from the Security Interest except as required or contemplated by
the Loan Documents.  Each holder of a participation in any rights under the
Borrower Loan Documents, if and to the extent the applicable participation
agreement so provides, shall, with respect to such participation, be entitled to
all of the rights of a Bank as fully as though it were a Bank under Sections
1.20, 7.02 through 7.06, 10.02 and 10.08 (subject to any conditions imposed on a
Bank hereunder with respect thereto, including delivery of the forms and
certificates required under Section 1.20(c)) and may exercise any and all rights
of set-off with respect to such participation as fully as though the Borrower
were directly indebted to the holder of such participation for Loans in the
amount of such participation; provided that no holder of a participation shall
                              --------                                        
be entitled to any amounts that would otherwise be payable to it with respect to
its participation under Section 1.20 or 7.02 unless (x) such amounts are payable
in respect of a Regulatory Change Enacted after the date the applicable
participation agreement was executed or (y) such amounts would have been payable
to the Bank that granted such participation if such participation had not been
granted.  Each Bank selling or granting a participation shall indemnify the
Borrower and the Administrative Agent for any Taxes and Liabilities that they
may sustain as a result of such Bank's failure to withhold and pay any Taxes
applicable to payments by such Bank to its participant in respect of such
participation.

that renders any provision of the Borrower Loan Documents prohibited or
unenforceable in any respect.

of the Borrower, the Guarantors, the Administrative Agent, the Issuing Bank, the

<PAGE>
 
Office, which account shall be under the dominion and control of the

the Swing Line Bank as security for the payment of the Contingent Reimbursement
Obligations and any other amounts that may become payable hereunder or under the
other Loan Documents. Funds deposited in such account, and any income thereon,

     A Bank that is a Non-US Bank and that has complied with Section
1.20(c)(A)(1)(bb) may, by written request delivered to the Borrower and the
Administrative Agent, have any or all of its Notes issued as Registered Notes,
and for this purpose the Borrower shall cause to be maintained a Register.  Once
issued, Registered Notes may not be exchanged for Notes that are not Registered

     Section 10.21  Foreign Currency Conversion.
                    --------------------------- 

     (a) Each reference in this Agreement to Dollars is of the essence.  If in
connection with determining the amount of a judgment to be rendered in a
currency other than Dollars it is necessary to convert a sum payable in Dollars
into such other currency, then, unless another rate of exchange is required
under Applicable Law, the rate of exchange used shall be the Administrative
Agent's spot rate of exchange in New York City on the Business Day immediately
preceding the day on which final judgment is to be rendered.  Notwithstanding
the foregoing, to the fullest extent permitted by Applicable Law, the obligation
of the Borrower in respect of any amount due in Dollars under the Loan Documents
shall, notwithstanding any payment in any other currency (whether pursuant to a
judgment or otherwise), be discharged only to the extent of the amount in
Dollars that the Person entitled to receive such payment may, in accordance with
normal banking procedures, purchase with the sum paid in such other currency
(after any premium and costs of exchange) on the Business Day immediately
following the day on which such Person receives such payment.  If the amount of
Dollars so purchased on such Business Day in accordance with such procedures is
for any reason less than the sum originally due to such Person in Dollars, the
Borrower agrees, as a separate obligation and notwithstanding any such judgment,
to indemnify such Person against such loss, and if the amount of Dollars so
purchased exceeds the sum of (a) the amount originally due to the relevant
Person in Dollars plus (b) any amounts shared with other Banks as a result of
allocations of such excess as a disproportionate payment to such Person under
Section 10.09, such Person agrees to remit such excess to the Borrower.

     (b) If any amount is received or recovered by the Administrative Agent, the
Secured Party or any Bank in respect of the Secured Obligations (whether
pursuant to a judgment or otherwise) in a currency other than Dollars, then the
Administrative Agent, the Secured Party or such Bank, as the case may be, may
convert such other currency into Dollars at the Administrative Agent's spot rate
of exchange in New York City on the Business Day immediately following the day
that such amount is received in such other currency.

     (c) For purposes of determining the amount of any Indebtedness,
Investments, Restricted Payments, Guaranties or other amounts under the Loan
Documents in a currency other than 

                                       59
<PAGE>
 
Dollars, such other currency shall be converted on the basis of the
Administrative Agent's spot rate of exchange in New York City on the Business
Day immediately preceding the date of such determination.
